Can you see hexagons … or octagons … something else?
An optical illusion based on regular octagons although the effect is of hexagonal-based prisms.
Making Waves evolved from playing with octagons. Look at the ends of the ‘columns’ in the photograph above. One end of each is obviously an octagon though it is in two colours - a dark, non-regular, hexagon and a lighter ‘curved’ piece. The darker piece gives the impression that you are looking at the end of a pipe or tube.
