Awesome!
woow, that is really freaky. i rekon those guys must have no life at all.
Actually most of the pen tricks in that video arent too hard, i can do most of them. Watch this video Japanese Pen Tricks. One of the people in it spins the pen on top of there thumb 13.5 times.
To keep this post on topic, I thought the artistic bicycling video was really cool, even though it seemed like some of the tricks got repetitive. My favorite was when the person stood up with both feet on the seat.
