Kscope is an app that uses your iPhone's camera to create live kaleidoscopic images. The app was launched on November 5th, so a box of 'fireworks' was sent out to the creative community and handed out in the street encouraging people to download the app and make their own personalised fireworks with the app.
With an additional push on Twitter and Facebook, a community started creating their own kscopes and a spectacular digital fireworks display took place at the kscope gallery: http://kscope.aub.ac.uk/
Kscope made the Best New Apps list on the App Store.
