Thanks for the link Carn. I've also stumbled upon pen spinning when broadening my searching to "twirl sticks".
I used this image
to great effect. I've been practicing for a few hours now and though I'm still spinning slowly, I'm doing much better. Now if only I could figure out how to stop the pencil from walking out on me... it seems that as I spin it, my fingers wander along the length of the pencil until I'm only holding the eraser.
But in any case, thanks for the info ppl
I can spin a piece of 2 ft long thin aluminum pipe quite impressively already.
