Cyclone by kRat 3/22/98 Cyclone is based on two simple algorithms, fire and 3D dot plotting. I wrote this in less then a day, but the code it was based on had been floating around my hard drive for a few months. This effect is featured in a demo 'Pyromania' that I may release some day. As of right now, it only has two effects (cyclone and some sin plasma) so it's not really that hot... If you want the source code, or would like ot chat about cool graphics algorthims my email address is killtherat@bigfoot.com Also, if you want more info on programming in general I'm the editor of the comp.sys.mac.programmer.games FAQ. It can usually be found at kRat aka Kill The Rat aka Kyle Ellrott
