The algorithm is based on noise generated from an FFT, and is moderately computationally intensive. I never got around to adding this to the islands, and the erosion code isn't really in a fit state to give out. Email me if you're interested. The other landscape code is islands.tar.gz . A quick perl hack to analyse the traffic in a newsgroup.
Analysis is broken down by author and subject-line.
See some example output . Get ng-analyse.gz . I never got around to integrating this with CDDB , largely because everything in CDDB is inaccurate or misspelled, and one would spend as long correcting the output as just typing it in. Get mkcdcover.gz . Essentially it emulates a sound card, but saves the stream to disk instead of playing it.
