"Attractor" flash game

It's been a long time since I've added anything to this blog's flash games category.  Here's one that will waste some of your precious time.  There are no instructions at the site, so you have to intuit the maneuvers, but it's easy to explain.  Press the little blue thingies to attract the white thingies and press the yellow thingies to repel them, trying to steer the white thingies into the red hole.  There is no scoring system or timer or penalties. 

I can't embed the game; you will need to play at this link.  I would favor a mute button to help maintain your sanity.
