A colourful, touch-reactive toy. Just touch the screen and watch the big, bright particles light up the screen and react to your swipes. Multiple touches introduce a centre-of-gravity that causes your particles to swirl around.

This was a personal project where I brought together some knowledge of OpenGL, from my days at digital agencies in London, on to modern devices such as the iPhone 4S and the iPad 2. This app is very graphically intensive and involves plotting a large number of particles using a meta-ball technique. The main aim of this app was to show that a seemingly complex app could be designed, built and deployed in under 2 months by constraining scope and focusing on user experience.

The app has just been released and is available on the iTunes App Store
