Moiré patterns are formed when two images with repeating lines or points are held or moved over one another.
Slide the mouse on the window to move one pattern on and off the lower pattern.
The apparent images that flash, move vertically, or at angles to the motion are moire patterns.
Discussion:
Are the patterns you see really there?
Are the patterns part of the way we see things and our brains put information together?
Why might your mind create such patterns and when could it be helpful in daily life?
