Your body moves the record

Vinyl Workout, by Theodore Watson is an audio/video floor projection piece that is interactive with how participants move on top of it. See Video of the piece in action. From the artist, "I designed this piece for the inaugural Rotterdam Electronic Music Festival. The idea is pretty simple. A giant record is projected on the floor and it can be played by running around its surface in the direction you want it to go. If you run slow the record plays slow, if you run fast the record goes fast etc.. Next version will have scratch mode." Additional interesting interactive works on the artist's website.
