nDroid reminds me of the intricate little "mouse houses" I used to draw as a kid. I'd fill an entire sheet of paper -- or mulitple sheets, taped together -- with the sideview of a wall in which dozens or hundreds of little mice lived in a complex and innovative world, consisting of chutes, and ladders, and catapults, and swings, and boy-versus-girl mice fights, with little mice bombs. I drew lots of them. I don't know why. Hmmm...I wonder if any of those still exist. nDroid is prettier, though. And more pixely.
