I like this one. At first you see a spinning clockwise female. Took me about 10 secs to force it to go anti-clockwise.

Funny. When I first looked, it was going counter (anti) clockwise. Took me about the same amount of time to get her to spin the other way.

Can't help but think that she must be horribly dizzy by now.

It took me a couple of attempts to see the direction change, I found if I concentrated on the feet It would change quicker.

Good one Snowy 

Yes very cool that. I first saw her going anti clockwise, took me a bit to turn her 

They picked a poor thumbnail for the video. I have a lamp like that, and recognized it right off.

Some good one's there. Didn't get the last one though - just a load of animated circles and then a lamp. 

The animated circles is one of them that you look at for a while then look away and your vision goes all strange, and the lamp is ererer rude, all I'm saying 

Hehe, I'll try again later then. 

If you look in your Youtube history at the small thumbnail of the lamp you should see what I mean 

Stare at the center of the circles for as long as you can without blinking, then look at you keyboard.

It should go all wonky in a trippy sort of fashion.

Thought this was a good one.

Very cool. Reminds me of those pavement artists.
