And you thought they were for writing. Pfeh!
Wow.
I'm sure you've seen it; some kid in class a couple seats over from you, spinning his pen around and around his thumb, or inbetween two of his fingers. Annoying? No, not unless he keeps dropping it, over, and over, and over. ; )
A couple months ago, I stumbled upon a group of websites, dedicated to enlightening the public to the art (yes, I said art) that is Pen Spinning. The above link will take you to a list of 'tricks' and 'combos' movies that literally look to defy physics and/or gravity. Take a second and be distracted - it might lead to hours of distraction and/or a new hobby for you.
Note: I'm currently stuck, after a week of concerted effort, on the 'sonic' and the 'charge' fundamental tricks. I've gotten the 'fingerpass' (and it's reverse) down fairly well, and finally 'nailed' the Thumbaround last night. : )
Oh - and Happy New Year; welcome to 2k6.
