ALSO lets not forget Ben "OMFG HE GOT POOP IN HIS MOUTH" Mathis http://www.poopinmymouth.com/3d/3d.htm One of the guys who got me interested in low poly, or better, 3d in general.
@Millenia: I recognized that immediately. It really reminds me of the concept art for that game. Also, answers as to what the 3DS can do... http://www.destructoid.com/3ds-gpu-can-do-impressive-things-177537.phtml
it's 4 planes (of two triangles each) with a "look at camera" tag in c4d. In the 3d engine they will be billboarded. Similar settings exist in all 3d packages / games although under different terminology's. Very handy for balls and so on.
