Cthugha pre-dated WinAmp visualizers by a couple of years, as it could take sound input from microphones and CDs. <a href="https://en.wikipedia.org/wiki/Cthugha_(software)" rel="nofollow">https://en.wikipedia.org/wiki/Cthugha_(software)</a><p>(This is a minor nitpick about the background, not the main part of the article.)
I don't think it's open source but this is easily the best visualizer I've ever used, in terms of graphics and simplicity in usage. And it's free.<p><a href="http://www.plane9.com/" rel="nofollow">http://www.plane9.com/</a>
Wow great write up! I do hope ProjectM attracts some newer maintainers as it still is an amazing modular music visualizer, on the same level of the Visual Light Machine work of Jeff Minter (see XBox 360’s neon viz).<p>Long live projectM!
