I just stared at that damned picture for probably 15 minutes.
Obviously, it holds something (vials?), and spins them independently while the whole thing spins. What purpose does it serve? Maybe for mixing...something? I don't know.
What's really confusing the heck out of me is why the one side of...um...holders? is all serrated and jagged. I just can't figure out a purpose for that.
Dude, donate some plasma or something and buy the thing. We must know more!
EDIT: Heck, I'll PayPal you $15 to buy the thing, just to figure it out and post a video or something. If, of course, it's still available. Didn't notice this was almost a week ago...
