What was the Mac program with vector graphics that kept time to music?

• Back in the very late 90s a friend passed along a copy of a configurable Mac program that acted as sort of a screen saver (but I don't think that was its primary purpose) that produced different kinds of firework-like vector graphics that moved and changed in time to whatever music you had playing on the computer at the time.There were a number of variables you could control, including the design of the graphics, and maybe the colors, too. I remember on a couple of occasions needing to get a new copy and the only place I ever found it was on Macster; I'm almost positive it wasn't commercially available, but it was probably shareware. I want to say it was German, but I may be thinking of the game Oxyd.Does anyone remember what this program was, and if there is a modern-day equivalent for Mac?

• Answer:

  I think I might remember the program (but I am not helpful because I don't remember what it was either). The designs were firework-like, literally (not psychedelic or kaleidoscopic) against a black background, and the colours shifted and changed but could be controlled, IIRC. It also came with a built-in tinkly soundtrack, if you weren't using your own music. If this is what you were thinking of, I thought it was Japanese in origin, and have been looking for it for YEARS. If not... good luck!
