TGC Competition 2006 entry - The Grand Machines - 3 level demo

Yesterday I submitted v.1.00 of my 3 level gameplay demo of "The Grand Machines" to the TGC 2006 Ageia Physx competition. The game is kind-of-a cross between Head-over-Heels and Marble Madness. It takes the co-operative 3d puzzle/platform elements of the first and the rolling ball physics of the latter. Yes, there are probably too many rolling ball games in the world, but it's been on my list o' game-things to do for ages.

EDIT: (Just submitted v1.1 - which adds a music track I created a few years ago.)
