If I was to walk into a mobile phone shop and demand a full size skateboard controller for my mobile or an interface to control an Etch-A-Sketch I wonder what they would do? Maybe they would laugh or insist that no normal person would want to do that or claim it can't be done. Yet last Thursday night in an unassuming corner of the east end of London, UK, I found people who were experimenting with these ideas and more. The event was the Push N900 Showcase, organised by Nokia, and I was delighted to be invited along. I even had a go at a bit of live video broadcasting with my trial Nokia N900 while I was there.
