Mid to Late 90's pong like game, controlled speed of ball, avoided obsticals for imac

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.
