I decided it would a fun challenge to try to make a program that produces nice looking fire. I ended up turning it into a game. The goal is to get the highest score possible by not letting the fireballs touch the bottom of the screen. I usually can't beat around 15 or so, but I don't have patience for these things.
Would you like to see the source code or download the program? You can get the files you need here. If you can't see the whole applet, you can press F11 for fullscreen mode or change your screen's resolution.
