Seems to me like something must've changed whilst you were moving your fonts there. You might try to restart and hold down option-v (before you see the happy mac). This puts you into verbose mode, which shows you all that is happening under the fancy GUI when the system boots. It just might, if you read fast enough, show you what's wrong. You could be able to ascertain at what point the system stops booting. Ahh... and then there's something about starting up in single user mode, but that's more complicated, and I really don't know very much about it.
