Nike: British 10K Run (Development)
http://www.youtube.com/watch?v=j5lzP_UKAT4
25,000 runners make it count in London. Powered by Nike+, runners hit the streets of London for the most interactive British 10K the city has ever seen.
EA: FIFA 12 Scarf (Development)
http://www.youtube.com/watch?v=lg8cC11U9vM
Users could get their Twitter message on the world’s longest fan scarf. They had the chance to have it knitted for real into a meter of world-record-breaking scarf. I created the 3D version of this using Flash, ActionScript and Pixel Bender. The project was quite challenging because of the limitation of these technologies. I managed to get it highly optimized using a variety of optimization techniques.
