Catacombs of Solaris is great for wallpaper generation
It's this program where it seems like you move thru a room.

I don't consider it a game, rather a program. I have made neat wallpapers out of images with it.
I have made it with the Revisited version on Steam. I guess I gave money to the guy so he can keep going. I just came back after almost a year so I'm trying to see how to do multiple images again.
