I see the problem with your matrix program. You're using counter to decide when to end, but you're also using it as an array index and preventing it from walking off the edge. So it'll never get higher than 8, and never end.
You're also preventing it from overwriting itself, i.e. changing any characters other than '.', so it'd be possible for itself to wall itself in like the worm game and freeze.
