Big Ideas (don't get any) from James Houston on Vimeo.
This is the coolest thing I think I've seen in a few months.
It's not a music video or just a remix. It's a music video documenting the production of a remix for Radiohead that uses only a printer, scanner, a broken hard drive and useless, tape-driven computer (that enormous squeal you hear at the beginning is the sequence itself being loaded, care of a tape-drive, and including it is a nice touch, but you'll probably want to wait for it to stop before passing judgement on this video).
Related, albeit definitively less cool music-wise but equally cool nerd-wise, is The Graphite Sequencer by Caleb Coppock, which I found out about here.
Caleb uses wires to brush over graphite on disks; as a result, you can "play" drawings. The result is less pleasing in terms of sound than the Radiohead piece, but fun to look at.
