I was recently editing an article about how to convert one format of digitized sound effect (rSound) to another (WAV). It's a pretty geeky topic, but one I think will appeal to the right audience.
Despite that esoteric pastime, even I have to say that some people have way too much time on their hands. Translating sound effects via digital means, I can understand — but reproducing Star Wars theme music "on the metal"?
At least this second example was mere happenstance and involved no real work… unless you count the unlikelihood of a Wookie amicably squeezing himself into a cabinet.
