When drummers get board. I did that stuff all the time when I was in High School. I was in the drum line in my High School marching band. We did a lot of those moves with drum stick for competitions. So when you were board during classes, most of us found ourselfs doing that with pens and pencils with out even thinking about it.
i can do the over the thunb tricks back and foward all day. one of the things i thought was kinda cool in hs and learned to do cus everyoen else did it. really pissed taeachers off tho seeings like 15 pens spinning at once in diff directions. some teachers petitioned that pen twirling be against the rules during class cus it was distracting...
on another note sed ur gonna turn into evil if you keep this up. might as well put all ur random finds in one thread next time and start a sed's random chit thread.
I wish I had enough free time to learn useless but cool tricks like this. This seems similar to the poker chip trick that I've been seeing on the world poker tour. I'd love to learn that and the chip shuffle.
