Any time two planes overlap (read: are not parallel), they overlap in one of four different ways: cranes, butterflies, atoms, or tangles. In the first three arrangements, it's possible to keep the poi rotating without interfering with each other. I'm pretty sure that any and all tangles result from the final atom shape. Here's a handy-dandy diagram that breaks this down in an easy-to-read fashion: http://www.drexfactor.com/sites/default/files/atomicclashes.jpg

A couple weeks ago, I posted a video of Arashi teaching a class at Firedrums and in it, I was struck by the fact that his "crane" atom had a strong resemblance to together-L in Maiki Nope's breakdown of atomic planes for clubs and poi. If this similarity bears out, it would mean in essence that there are 3 different atomics that can be spun from a variety of angles, depending on the perspective of the viewer. Atomic spinners: how does this gel with the world you play in?
