Det går an å få henne til å spinne både med og mot klokka.



How to get the spinning girl optical illusion to work


Let me say straight off the bat, Guy thought for a long time that the dancer could only possibly spin one way clockwise. Three things helped me to see her spinning both ways: belief I WILL GET THIS TO WORK. Also, a practical point, the first picture I studied had the animation running too fast. So the slower the spinning, the better your chance to see this illusion. One more tip: try focusing on the left edge of the picture, then slowly pan your eyes to the right. This is how I got her to spin clockwise. Will said that looking at the dancer's feet helped him to the her turning anti-clockwise. John said that with the spinning girl optical illusion it was concentrating on the shadow that enabled him to switch directions.

Forøvrig: Det er også mulig å se Che i den jesusillusjonen...
