The May 2005 issue of Popular Science has an article on Munich’s annual Recorder Race. It’s a competition of classic Walkman/Boom Boxes/Ghettoblasters that have been modified with wheels, gears, spoilers, etc. so that they can race each other down a 15m gym floor powered by their tape drive mechanisms. Obviously they would all want to run in “fast forward” mode.
