Moiré Patterns

In mathematics, a moiré pattern (or moiré fringe) refers to the interference phenomenon produced by two patterns made of similar geometric figures. Wolfram|Alpha can visualize the moiré patterns in the shape of square or hexagonal grids, with options for specifying rotating angle and/or shifting distance.
