I always wanted to code “Plasma”, a color palette fx seen a lot in demos of the good old C-64 and Amiga days. I haven’t found any good example on the net, but a friend of mine gave me some hints and so I did it. The example should be easy to understand, if you have any questions – drop me a line! You can let it run in your browser with the included java applet.
