Wow! It does work!

Well this isn't so much to do with your eyes, but it's really really freaky!

My colleague told me this from work:

Turn your right foot clockwise (like make it draw a cirlce in thin air) for about half a minute, then write a number 6 in thin air with your right hand (whilst still moving your foot).

If you have done this correctly your right foot will automatically turn anti-clockwise!
