You're about to watch a video of Performer. Know first that it's an iPad app that lets musicians control their instruments by moving shapes around in real time. Know second that you are definitely tripping out.
Keep in mind, also, that this is pretty strictly professional-grade. It connects to any instrument that receives OSC or MIDI inputs (so you'll need to have one of those handy) and the app itself is a hefty $30. But for the chance to transform into a Daft Punk music video any time you want? Might just be worth it. [iTunes via FastCo Design]
