Machinarium

I found this game while browsing through the steam client (love that thing, it's like a videogame iTunes). It's a point and click adventure, but it's just great. You can see that the designers were a bunch of artists who poured their heart and soul into it. You play a little robot making his way through a robot city that looks as though it was designed by Dr Seuss. Great, especially if you're a stoner, trust me. It's just beautiful.
