Moire patterns are interference patterns. Classic moire patterns are made by overlapping two series of concentric circles. Some of these patterns are made by the interference between circular images and square pixels.

Color Moire | This is a classic moire pattern made by overlaying three fields of concentric circles (one for each color component), each slightly apart from the other. |
 |
Gray Moire | The moire patterns scene here are the result of interference between the circular pattern and the square pixels, which don't have sufficient resolution to display the underlying pattern. The effect is reduced considerably if "oversample" is turned on, which increases the effective resolution. |
 |
Polar Moire | In this case, we're using the angle function to display a series of lines emanating from the center, but since there isn't sufficient resolution to display the lines, moire patterns result. The effect is reduced considerably if "oversample" is turned on, which increases the effective resolution. |
