Rotational Symmetry: from the Maskworx Magic Box

Symmetry is a way that units of pattern are organised. A pattern is symmetric if you can copy it, move it to a new location or orientation, and place it so it exactly matches the original. There are many two-dimensional symmetries but here we will examine Rotational Symmetry - using masks in repetition.

Rotational Symmetry occurs when a series of masks is rotated around a center point. The number of repeated elements can vary. In this case there are seven winter carnival masks repeated until a new image is formed which resembles a 'snowflake', a good example of rotational symmetry found in the natural world.
