BigWheels was a demo me and 2 other students made when we worked for Grin for 10 weeks. Most of my time went to learn and hack their API and make the Fixed Function Pipeline into a vertex/pixel-shader centric engine. I succeded in doing that but I didn't have time to make any cool stuff with it.
Only thing I had time to make was a ground-fog effect.. here are the shoots. I you wanna play the demo, well, it's big. Send me an empty cd-r and a stamped envelope and you might get the pleasure of playing this unfinished game. :)
