This is just a quickie, but since we're still discussing Unconscious Processes (this morning's post), check this out.
This bit of strangeness came from here, where it was much more artfully presented. But here's the text of it:
While sitting at your desk, lift your right foot off the floor and make clockwise circles. Now, while doing this, draw the number "6" in the air with your right hand. Your foot will change direction and there's nothing you can do about it.
Try it folks. It's really weird. Can any of you Resist This and make your foot keep going clockwise? No luck over here!
There is probably an explanation for this posted somewhere, but the explanation is probably not nearly as interesting as the phenomenon itself!
