While it's hardly a game in its current form, it somehow feels incredibly calming watching the cars move back and forth through an ever-morphing city. Is it inspired by the "Labyrinth"-boardgame? I considered doing something similar, but eventually ended up dropping the idea. One can still sense the influence though when looking at the different room layouts in my game. Also learned on that occasion that the boardgame seems to not include any crossroad-tiles. :D
