So in the 90's I used to play this game on my family's computer, an Apple Macintosh. I guess if I had to pick the genre I would call it an arcade game, though this is difficult since I can't remember what the objective of the game was. I remember that it consisted of vibrant backgrounds of geometric shapes, against which smaller shapes moved in the foreground. For example in one map i think there were four rectangles filling up the back screen, and they are well-shaded 3d-looking rectangles, not cartoonlike. I think they were green, though maybe they were multi-colored, or even of changing color and pulsating. The shadowy area at the bases of these shaded rectangles serves as a valley in which a tiny little ball travels. Based on my family's taste in open-ended computer games in the 90's (Manhole, Spelunx, Myst), I'm not even sure there was an objective other than to mess around. It was great fun and had intriguing music, but I can hardly remember anything other than the sensation of playing the level I attempted to describe. I will attempt to provide more details if asked! Please help, because I feel like this game formed some part in my psyche and would love to play it again (or at least look at screenshots and compare them to the images in my mind). Thanks for your time.
