Blokz RAVE is a new 3D game written for Mac OS 9. It is inspired by Tetris, but it's more of a tech demo than a tetris clone.

Blokz RAVE requires a physical mac with a G3 processor, and a hardware accelerated graphics card. If you have anything newer than an iBook G3 Tangerine, it should run fine.
