Claudius Maximus, is a London based artist and programmer. He works in both the audio and visual realms, often with elements of live performance or algorithmic generation.

I discovered Claudius through his role as a moderator on the Pure Data forums, but he also uses a variety of other programming tools, including lua, haskell, and supercollider. He also has written his own command line torrent builder.

It appears that he uses only free/libre and open source software to create his pieces, which are then hosted on archive.org under a creative commons license.

The latest post on his website is a drone audio piece called Cathedral Algorithms, a recording of a live performance from the latter half of 2009. I find it very meditative, in that dissonant way unique to drone music and working around heavy machinery. Check it out.

UPDATE 06-14-2010: Claudius Maximus has now uploaded a video to accompany the Cathedral Algorithms audio track.
