Back in middle school I played the clarinet [1]. The first year, I rented an all-plastic clarinet and had trouble understanding why the other students had trouble getting a nice clear sound out of the instrument. It was the following year when my Mom got me a real clarinet that I found out just how difficult they could be. I ended up faking my way through the rest of the that year and never bothered to continue playing the instrument. Of course, that didn't prevent me from playing the electric clarinet during college (it's a joke—some friends and I formed a joke band [2] called the Blender Children [3] (also known as “The World's Most Dangerous Peer Group”) and threatened many times to go on tour).
So I'm amazed that what looks like high school students actually made an electric clarinet. Or rather, a robot that can play the clarinet [4] (link via kisrael.com [5]).
Wow.
