Plasma Applet
You can find my new (or should I say rereleased) Plasma applet from Applets section. The applet creates plasma effect with two precalculated color tables. The precalculated tables use sin and cos functions to generate beautiful plasma-like image. The precalculated color table is also used to fine tune the rendered result. Source code is included in the zip package. Take a look at the Applets page.
