Nike makes a collection of musical footwear

Nike created this evocative promo piece called nikefreemusicshoe that turns a collection of footwear into musical mixers. Bend twist and squeeze the shoes to mix tracks and create compilations on the fly. Amazing promo concept, however, why aren't they actually wearing the shoes? I would love to see full body dance and movement that results in a custom mix. Nontheless, this project has sucked me in and I want to play! Go to the nikefreemusicshoe site to watch the video.
