Not sure that you guys can remember or seen the mid-late 90's OpenGL tech demos and stuffs. Like GlClock. Or the one which featured moving gears which I can't name right now. Or the basic hardware T&L sample demos where the teapot and the torus model was often used... Or the origin of the Serious Sam game. OR THE 3D WINDOWS 95-98 SCREENSAVERS. Yeah, but these made at least 20 years ago... Not even mentioning the GeForce 2 / Radeon 9800 tech demos which were awesome at their time.
But calling this a game is an over-estatement. You just have to pause an automatically transforming model whenever you want to get achievement + idling it... There's no actual interaction. And not sure what's taking half of gigs. I mean this would fit in a few megs of OpenGL script...
