Manufactoria

[deane]

matthewdaly recently turned me on to Manufactoria, an online game in which you ostensibly build factories for testing robots. In reality you're programming a Turing machine in which state is determined by position on the factory floor.

I'm quite enjoying the game, but it wasn't until after I'd already solved the first 28 levels that I discovered, while looking at someone else's solution, that you could make conveyor belts cross.

Good lord. That certainly makes things easier!

Heh. You can also reverse the red/blue branches by pressing space, which didn't strike me for a very long time.

Speaking of making things easier, I solved all the levels and then looked at someone else's solution to see how clever people popped a character off the back of a string. Which was, um, about a quarter of the size of the way I had been doing it. Then I cleared my levels and started again with that new knowledge. Wheeee!
