This has been discussed on the cafe, and I believe I can post this response without exposing the method to those who do not know Motion or SPIN.
SPIN credits several effects within it including Motion and stands on their shoulders as a journey into how far to push an old method. SPIN is a way to "SPIN" large objects and objects people would never think to move, with your "mind", many times causing them to spin quite rapidly. It happens to also be able to move a pen as one of the many things you can move.
Think of it not as a new effect, but an exploration that pushes the limits of the old method to see how far it can go, including new "force technique" "Setting it free" and routining ideas, with all credit given where it is due. I hope that helps. Best wishes! -Matt Sconce
