There was this game I used to play at a DOD school in Okinawa Japan around 1990-1994. I believe it was on a Mac but I cannot be sure (my memory is really fuzzy around that time). Anyways you direct a ball or a marble around an obstace course. The graphics were pretty good and the game was very addictive. I wish I could be more detailed.....

Time to search the internet some more. Hope someone know's the game I'm talking about. If they do hopefully there's some way to run it on current PC's perhaps with Basilisk or something (if it was for Mac).
