Remake of classic style Fireworks

This is a remake of fireworks I did in GS1 years ago, before I could go on Testbed to learn GS2. Please, don't state the obvious, that I didn't use the built in particle engine, I'll work on it later... maybe. But any other comments are welcome.
Also thanks to Door for helping me make it prettier. And all the Testbed Server people for allowing me to learn GS2 there. And for everybody else in IRC who logs into testbed just because I say help I need a body to test on!
