Mid to Late 90's pong like game, controlled speed of ball, avoided obsticals, had to get all of the rectangles with the ball, bouncing off the walls to do it. I think it might have come with the first imac, but i'm not sure. I used to play it in school during break around 1998. If you can remember it you are a GOD. Keep thinking that Jewel was in the title, but can't turn up any results.
