Brain usage

[Senethior459]

But unless you watch it carefully, it certainly seems like it.

Just watch it for 5-10 minutes. It will change direction 2-3 times. Trust me it does. Watch which foot she has down and which in the air, it will switch when she changes direction (thus proving it is in fact NOT a brain usage thing).

I can see it change direction probably 50-100 times in that amount of time... It doesn't
just randomly change directions... Seeing how for me I am able to just cover up part of
it and it seems to go the other way... and everytime I do it... Whether or not it has to
do anything with which side of the brain you use, well I don't really know... But I do know
it is definatly not random...

"shrug" I just explained the trick, believe it or not at your leisure.

It's not so much a trick but more of an optical illusion....
It's really just going back and fourth, but tricks you into
thinking it really is going one direction then going the other...

Anyways here is a good artical on it...
