INFORMATION SURFACES

to illustrate the concept of ROTATABILITY

3 x 3 Design - Not Rotatable

2 x 2 Design - Rotatable

Notice "Pockets" of excessive information - and that, the information surface does not show circular symmetry.

Notice the circular symmetry of the information surface - same information regardless of rotation angle.
