On a related topic, the author's game LOVE is worth checking out -- a very evolutionary and programmer oriented (no surprise here) approach to game development. Check out this demo a few years ago of the tools he created and of the game. I haven't followed the game in over a year and when I played it was a bit broken and made me lose my vision for a few days but still worth checking out. Reminiscent of Minecraft actually and released around the same time.
I hoped LOVE would get traction, but felt it didn't work for me because it was too unconstrained (no clear objectives). I don't know how Minecraft has solved this.
The visual style is such that it looks like a painting viewed through a sand storm through a camera with a lens smeared with vaseline. It looks amazing initially but literally is painful to look at for any significant amount of time. I think the developer essentially takes very basic geometry at low resolution then layers on graphical affects.
You may think that looking at the gameplay demo that the game was simply recorded at low resolution but that is not the case. Bump the video to 720p and full screen then that is actually what it looked like at the time. Not sure if it has changed since the last time I played.
Love is beautiful in still shots but the actual game gives me motion-sickness. Even Mirrors Edge, which is renowned for being vomit-inducing, didn't have that effect on me. I think it's because the background just won't stay still.
