A sinewave animation package written in Common Lisp. You can specify parameters for the sinewave such as origin, frequency, amplitude, phase... and the software will output image sequences of a sinewave. There is an option to connect points on the sinewave with lines of a given stroke and color.
I'm not hosting the package as a download, but if you're interested in using it send me an email and I'll probably be happy to send you the package.
