Saturday Synth Porn: Get In Touch is an installation designed around the idea of using a nude body as a musial interface:
The installation consists of a big white cylinder shape, with human backs coming out of openings in the fabric. Visitors are invited to touch the backs to create sounds. When you touch two or more backs, a connection is made and you can start playing. To change the sound you apply more pressure. You can touch different combinations of backs to create new sounds.
Get In Touch was made by Cocky Eek‘s Tactile Research Lab, and is intended to “question the way an interface influences behavior.”
