Its hard to explain what this actually was. I guess you could call it a musical beat box but that would only partly explain it. It was a stand produced by CokeCola in the olympic park. You could walk up the structure touching these panels (hence the ingenious name) and they would play a sound effect from one of the sports in the olympics. Yo could mix them all together to produce something like MArk Ronson who used these sounds for an olympic song.
