This is rather impressive. Virtuoso Chinese pianist Lang Lang is known as a bit of a show-off already, but at a recent San Francisco concert he pulled out an iPad for the encore and proceeded to play the ridiculously complex Flight Of The Bumblebee. Thank heavens for multi-touch.

It's not clear exactly what app he was using for the trick, but a commenter on the YouTube video suggests it's Magic Piano. How long will it be before the likes of Gary Go switch from their iPhones to the iPad?
