While sitting at your desk, lift you 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. Ah well, Happy New.Year.
Thank you for that,sir.prize. I've seen a few optical illusions. Have you heard of the "electric brae" in Ayrshire Scotland? If you stop your car on this brae(hill),turn off the ignition your car appears to roll UP the hill. If you google "electric brae" in Ayrshire you can read about it and get the explanation.
