Moiré Motion Illusion
You must try this illusion. The horse appears to gallop on your paper as you slide a transparency with a grating printed on it over the image.
- An overhead transparency sheet that you can print on. Copy shops can photocopy onto transparency sheets if you don't have any. As a last resort, you can print the images onto regular paper and hold them in front of a bright light.
- Print out the pattern once on paper and again on an overhead transparency.
- Cut out the rectangular grid of lines from the transparency and place it onto the picture of the horse on the piece of paper.
- Slide the grid from left to right over the image to see the horse gallop.
