I was checking out a few live music viedos of Joel Zimmerman (deadmau5), when i came acrose one of his live shows showing him playing at a live consert with some kind of giant touch pad for music, usally he play in a visualizer cube called a mau5cube that haves what it does shows viedos while he also plays music, so to find him not playing in the mau5cube was a little weird, but this new devise called the Holo Desk is said to be the futuer of all kind of music so heres the links for the deadmau5 consert with the holo desk and the youtube channale for the holodesk. (ps i didn't post these only found them.)
