The only weird board that I ever came across was the 1920's "Ondes Martinot". Not really the keyboard itself, but things like the "Palm", "Resonator" and of coarse first ever made ribbon control. Most of that stuff looks pretty impressive. Especially the "Resonator". I wish I could get a hold of one of those. It's suppose to be awsome for making all kinds of drones, gongs and other cool stuff. I think that's what they used in the first "Star Trek motion picture" to make the big gong like sounds/drones. Heavy stuff.
