For Christmas, Punch received a game called Mind Flex, the object of which is to control the speed of the fan with your mind in order to get the ball to float at different levels and maneuver through the maze. In both pictures you can see the ball floating.
It gave me a headache and left a dent on my forehead and felt, just a tiny bit, like being constipated.
I found it to be creepy but Punch thinks its grand.
