milking simulator rofl. i used mass-springs "a lot" in audio, i was probably thinking second order solution for years before considering making a game :)
there was a gary larson/far side panel of a scientist with his face in a pair of boobs on a panel on the wall. i think of that a lot :)
i always wondered why i didn't see more sex video games since the 80s, like zaxxon with dicks and stuff. or like centipede with... no, ok not that. i'm just doing flying birds now but i was thinking volumetric tetrahedral meshes would make awesome boob sims. maybe squishy lavish bb2 or just like two big boobs and some cursor object to squish them around with for 30 seconds stress relief. boobs boobs boobs rofl :)
