[math-fun] Wicked double maze puzzles

Ow, these simultaneous mazes make my head hurt: http://durota.ru/games/0/451/play.html?category_page=10 They're only tangentially mathematical, although it's interesting to contemplate an algorithm to solve them. Normal maze solvers never seemed too impressive to me, and I wonder if the computer might be significantly better (or worse) than humans on simultaneous mazes.
