Bouncer is a 3-dimensional simulation of a bouncing ball written in Creative Solutions' Multi-Forth. The unarc'ed size of the file is on the large side because I haven't taken the time to strip out all the extra baggage. The application was compiled on top of the default Multi-Forth system, then turnkeyed, so you can see that Multi-Forth by itself isn't very large.
The source is largely the same as that which appeared in Volume 2, Number 1 of Amazing Computing. I cleaned up a few things and randomized the initial velocities. The major shortcoming of the demo is lack of sound effects. I have done some work with audio in recent issues of the magazine, and I expect to go back and add stereo to the Bouncer sometime soon.
