Software turns up illusion

  June 23/30, 2008
The right patterns in the right colors can produce the illusion of motion, and over the years scientists have figured out how these repeated asymmetric patterns work on the brain's visual system. Software that generates images using these rules dramatically enhances the effect.

The software can be used to make images that look like they are moving.
