Remembering A Title

I'm having a very hard time remembering a certain game title. It's one of those new physics games and while you're going through it you feel more like you're in an art museum instead of a game. I also remember that there wasn't a whole lot of color to it either. Mostly blacke and white. I can even remember watching a Totalbiscuit video review on you tube about it and after watching that it made my mind up for me. Could somebody please tell me what it is?

Could it be powder toy?http://www.youtube.com/watch?v=oL44XRsemEQ

Thanx for trying but that's not it. I'm wanting to find it realy bad too because not too long ago my external HD did a total melt down and it was on that drive! Needless to say I'm missing it terrorbly!

Unfinished swan is mostly a black and white fps puzzle platformer game, might that be the one?
