I was just barely working on a pacman clone about two months ago... turned into mostly just research. It turns out the ghosts follow rather simple patterns between two modes (spread out / attack) which turn into complex behavior, mostly due to how they interact with each other.

I found this thread very helpful for the Ghost AI: http://www.atariage.com/forums/topic/68707-pac-man-ghost-ai-...

was the best guide I found, its brilliantly in depth and covers more behaviour than I ever realised, like how the pacman turns corners. Pity I only found it after I mostly finished it.
