first, it call Penspinning.
Second, other than XB2 and a Japanese penspinning dvd, there are NO penspinning dvd in the world. Which is whats so great about penspinng cuz you can learn it free.
Third, go to this youtube channel:
http://uk.youtube.com/user/akujinnoeso
That guy has the best ps tutorial in the world.
Fourth, learn the following tricks first:
Thumbaround
Finger pass
Charge
Sonic.
Then learn there reverses (reverse thumbaround, reverse sonic, etc) then learn advanced tricks.
I've been penspinning for about 5 months so if you need any help fell free to pm me.
