Two years ago the proportion of the world's population living in cities eclipsed those living elsewhere for the first time in history. The trend has persisted, in fact it seems an unstoppable juggernaut with the ratio predicted to reach 3:1 by 2050. Of course, city-dwelling is nothing new, but cities that 20 million people may call home certainly are. As Justin McGuirk discusses in this article, the transformation presents some of the most profound design challenges of our era. The process of regeneration is relentless - you can't go far in New York or London without seeing immense construction work underway, or derelict buildings whose future is no doubt already a glint in the eye of some ambitious developer.

So, as John said, the question at hand is: how do you wow the un-wow-able without alienating the familiar? It's a tough question, and here at Cogapp it's our job to try and answer just that question. We understand better than most the phrase "appropriate technology" - when to hide technology, and when to show it; how technology can be used to enhance an exhibition without overwhelming it. Ever since we developed the first museum interactive almost twenty years ago (in the form of the National Gallery's Microgallery) we've been creating new technology and developing new ways of implementing it; advanced hardware and software deployed behind an intuitive user experience is what we do. We're constantly trying to find new and exciting ways to do it. From creating award-winning vivid and instinctive installations for the Great North Museum, to bringing Prudential's corporate archive and stories to life with expansive sheets of Holopro glass, pushing the envelope is never off our radar.

Museums, by their very nature, are often thought of as being places where people go to discover, reflect on and learn more about things of the past. Even museums that are focussed on modern times or even the future tend to impart knowledge of the way things are through the use of artifacts. So onlookers tend not to think of them as places of technological innovation. But in their bid to attract ever-greater audiences to their exhibitions, museums are constantly striving to create ever-greater installations for said exhibitions to instigate the 'wow' factor that will get visitors talking about (and, equally as importantly, recommending) what they've seen. Given that one of the central remits of a museum is to educate and inform the masses, bringing in the audiences is vital to their mission statement. And so it is that in their drive to create more revolutionary exhibits, museums often become incubation units for rapid changes in technology. The irony of this is that visitors having an enjoyable, easy and relaxing experience is so integral to museums that the technology needs to be implemented in a smooth and efficient way. So much so in fact that it mostly goes unnoticed. It's such a fluid experience that the technological innovation happening under a visitor's very nose is more often than not completely under-appreciated.

2010 is billed to be the year of many things: the tablet (if Wired and PC World are correct), the smartphone (going by some analysts and journalists), 3D TV (according to some) and of course, the Tiger (no relation to Apple's OS though I'm afraid). However, with all the hype and speculation, one trend that will be making its public debut in 2010 that has so far been missed by critics and foreseers alike is the new art of facemunging.

Before you recoil in horror trying to dream up the possibilities of what this might be, allow me to elaborate a little. But, in line with the old adage that 'a picture paints a thousand words', allow me to do it with an image. It's not a pretty image by any stretch of the imagination, and for those of you who know Ben or Eleanor personally, this will bear an extra, far more disturbing weight than usual. However, it displays perfectly the power of facemunging. Be warned; what follows is not for the faint of heart.

Ready? This is your last chance to turn back now.

Okay, here goes (but don't say I didn't warn you):

If you're one of the nation's 5 million BBC iPlayer users (or perhaps, for our US friends, one of 40 million Hulu users) the murky boundaries between 'using the internet' and 'watching TV' will be familiar. From enjoying shows online to - in the near future - reading news and catching up on e-mails on our plasma TVs, the magical process of 'convergence' is charging its way into the new decade. When you can sit on the bus and watch live TV with the rather spiffing TVCatchup, you know the days of bluntly differentiating between computing devices and TVs are numbered.

Technology firms hoping to catch such disruptive waves of change meet annually at the Consumer Electronics Show in Las Vegas, boasting the wares they hope will enter our homes in coming years. It's a veritable trend-seekers paradise, and one particular trend at this year's event leapt out (almost literally). 3D TVs, capable of showing the new breed of 3D films like James Cameron's Avatar in all their splendour, will eventually find their way into our living rooms. That alone is revelatory, but in parallel with the convergence stampede presents one huge floating 3D question mark for interface design.

Experiments with 3D interfaces are not new, but have begun gaining traction with the emergence of gesture-based devices, particularly multi-touch devices like the all-conquering iPhone and Microsoft's Surface. One approach I've been watching with interest is BumpTop, revealed with an eye-opening TED talk (listen to the oohs and aahs) and now available to the public.

To those of you looking for Top of the Pops who have come to this blog-post accidentally I say "fret not wandering searcher", for you have stumbled upon a treasure far more substantial than the much-mourned TOTP. You have stumbled upon Cogapp's TTOP: Tech Tuesday Outreach Program.

Firstly, let's a get a bit of background out of the way. Tech Tuesday is a fortnightly occurrence here at Cogapp central. The Technical Department gather round Japanese food in our conference room and discuss all manner of tech related trivia, from iPhones to ICONS and anything else they're musing about. This has tended to be the realm of the digital gurus, technological masterminds and computational wizards in the past, but this week Tristan decided to mix things up by opening the invitation to the entire office (and holding Tech Tuesday on a Wednesday, but that's less dramatic). Not only this, but having recently been to Brighton's Over the Air event, he had been inspired by the presentation given by Tom Hume [http://www.tomhume.org/] (MD of Future Platforms [http://www.futureplatforms.com/ ]) and Joh Hunt [http://bluejoh.com/] (a postgraduate research at the University of Sussex) called "Many Paths to the top of the Mobile Mountain". So with material generously lent to us from Tom and Joh and an invitation to the hallowed halls of Tech Tuesday extended to everyone, we descended upon the gathering. With almost all of the Cogapp team involved, Tristan had a much larger audience to demonstrate his digital delights to; the Tech Tuesday Outreach Program had begun.

Tristan started with background information and a brief about what we were going to be doing before swiftly moving onto the main event of the TTOP. "Many Paths to the top of the Mobile Mountain" is a group exercise designed to get people of different backgrounds working together on one project at the same time. This interdisciplinary approach creates a hotbed of creativity and ingenuity as ideas are proposed and almost instantly analysed by experts in various fields. With specialists from design, tech, production, user experience, finance and business development all bouncing ideas off each other, the inventive juices really got flowing.

But enough of the build up, "What was it you were actually doing?" I hear you cry. The exercise splits the group into several teams (in our case, 4 teams of about 5 people) and introduces us to the fictional Jeremy, a 34 married civil engineer with 2 young children. He is a novice in the world of mobiles - using his allocated texts, minutes and data allowance sparingly - but considers himself technically aware. He is dyslexic and enjoys nothing more than exploring his local peak as part of a spot of mountaineering. Each team was asked to design a mobile application for Jeremy that would allow him to interact with his workmates and family whilst on a mountain, and given a swanky dummy mobile on which to design it.

The teams all went to different corners of the office and got prototyping. Whilst I can't speak for the creative methodology behind the other groups, we had a discussion and created a Journey On- inspired mountain route planning and sharing application that we dubbed Journey Up. After hours (or minutes) of intensive (or lighthearted) prototyping, we had our idea, and we welcomed Mr. Joe Baskerville from a competing team for a bit of vigorous (or easygoing) user testing. This part of the exercise really highlighted the necessity of even the smallest amount of user testing, as clearly apparent but previously unidentified kinks in our product were brought to light by Joe's scrutinizing eyes.

After a reconvening session where teams displayed their designs so far, the proverbial spanner wasn't so much thrown into the works as it was hurled in with wild abandon as Tristan instructed us to swap the mobiles on which we were developing our apps. In all cases this completely changed the capability of the technology with which we had been working. All the teams had to adapt their development to accommodate the new technology and whilst some (a campfire emulator was adapted to incorporate a music purchasing program by one team) were more successful than others (Journey Up took a big hit when GPS was removed from our phone's spec), it showed how important it is to keep the wider audience in mind at all stages of development.

After a quick discussion of the lessons we'd all learned and a riotous round of applause, TTOP ended. Hats off to Tristan for a brilliant and welcoming Tech Tuesday, and indeed to Tom Hume and Joh Hunt for creating an imaginative and thought provoking exercise (read about their successful running of the event here [http://www.tomhume.org/2009/09/mobile-mountains-over-the-air-2009.html] and here [http://www.tomhume.org/2009/08/agile-2009-many-paths-to-the-top-of-the-mobile-mountain.html]).

A few weeks ago I was lucky enough to attend i-Design, a one day conference and showcase for anyone with an interest or passion for interactive design and the digital arts. The programme certainly lived up to its aims as I came away truly inspired and entertained as well as being somewhat perplexed too!

The day kicked off with a panel debate centred around the idea of ‘Post Digital’ asking the question, 'If everything is digital, then what's next?' In a world where everything references digital media, how does our industry need to respond? This was a fascinating insight into the minds of the panel members more than anything, with the illustrious Adrian Shaughnessy leading the discussions.

This then lead the way for the first 5D interlude of the day by MOTH who beautifully showed their passion for experimental technology and for pushing the boundaries of traditional VJing. MOTH bridge the divide between video mixing and street art, generating site-specific video graffiti designed in response to the morphology, texture and ambience of the spaces and structures of the outside world.

Another presentation that particularly caught my interest was one by Lichtfaktor. You might recognise the work of these lords of luminosity from the TalkTalk television adverts (which also bookend each segment of ITV's popular X-factor). Their work in light-writing is spectacular, ranging from relatively standard incarnations of the practice, through to an amazing light-printer that allows pre-written messages to be created and captured in the same way as standard light-writing.

Last week I put "W1F 0TF" into trusty ol' Google Maps and found my way to the Slug & Lettuce on Wardour Street for Chinwag Live's 'Search is Dead, Long Live Search' event. Examining some of the key challenges currently facing search engines, and what these may mean for brands, web companies (not least SEO agencies) and users in general, the lively panel discussion helped crystallise some ideas I've been pondering in recent times.

Just as the ferocious 'Browser Wars' continue to rage, the fight for search engine dominance remains in full force. In the West we are so familiar with you-know-who that the word 'Googled' is poised to become the 21st Century 'hoover' and lose its capitalisation, so we'd be forgiven for thinking the battle effectively ended some time ago. But step away from the primary colours; the story isn't so simple.

First, look to the Far East where the landscape is remarkably different - Baidu holds a mountainous 69% in China, while Google has only a hilly 25% (July 2009). Second, stop thinking about search purely in terms of the 'traditional' search engines, since these now represent only one of many powerful ways to discover content, and the picture is less clear.

No, this isn't the new craze in ballroom dancing, nor is it the first attempt at communication with alien beings. It is something altogether more exciting! Bear with me and I'll reveal all...

Thursdays are always a much anticipated day here at Cogapp HQ. It's nothing to do with their proximity to the weekend, nor are any of us fans enough of Thor as to warrant getting excited by a day named after him. No - the fourth working day of the week heralds the arrival of Cake Thursday for all Cogapp kind. At 4 o'clock on this hallowed day, we all gather together for a bit of time over cake, tea and all manner of other delicacies and discuss what we're all getting up to (in between bites of dessert-y delights of course).

However, whether it be due to anarchy or inspiration, our Technical Director Ben suggested that instead of the normal occurrence of informal chats and exchanges, last week's Cake Thursday (yes... I am going to insist that 'cake' be capitalised in this instance) be dedicated to a brief session of Pecha Kucha presentations, cunningly titled Pechapp Cakecha (... see what we did there).
