The owl project

I read in this months issue of The Wire magazine about a strange noise/woodwork project called "The Owl Project". It started when 3 dudes sitting round a campfire decided to record owl sounds with a casio SK-1 and played the recording back to the owls, who then swooped down to see what was happening. By embedding circuit board into bits of trees they then invented their own instruments, The Ilog, The sound Lathe and The Log SK-1.
