Violinist plays Mario soundtrack in real time

In this video, violinist Teppei Okada plays the soundtrack to a real time Mario game live on his instrument. This — as do most creative geeky Japanese videos — was first made popular on Nico Nico Douga. I wonder if he coordinated the moves with the person who's playing the game. Either way, it's pretty impressive.
