They’ve just covered this over on the Foundation blog so I thought I’d share it with you.

YouTube channel owner Arganalth plays music. On old disk drives. It has to be seen to be believed. He’s recently moved from PC/Arduino to the Raspberry Pi to drive the playback and his latest is the Back to the Future theme (see above). Read more about it, including the tutorial that led to him doing this, over on the Foundation’s blog.
