The idea for this came while playing Rock Band. You need 8 limbs to play everything. 2 hands for the guitar, 2 for bass, 1 hand for the mic, 2 hands and a foot for the drums. An octopus could do it. A rocker octopus! And so the Rocktopus was born. Get your Rocktopus T-Shirt at www.detourdesignables.com
