Illusive Concentric Circles

My op art piece Trinacria (1997) features three black-and-white zig-zagging shapes spiraling together to create the illusion of interwoven concentric circles. These jagged, repeating patterns add a sense of depth to the piece and produce a subtle rotating effect that seems to shift as you follow each line with your eyes.

Prints and canvases of Trinacria are available in my online gallery.

Below, an animated version enhances the effect. By focusing on the center, viewers can observe virtual circles appearing to move inward or outward, adding to the piece’s dynamic sense of rotation and depth.

Would you dare run on it?

This wavy floor is actually a mind-boggling optical illusion that discourages people from running down the hallway (in fact, the floor is a completely flat surface!).

Manchester firm Casa Ceramica used a neat combination of black and white tiles to make the floor along the hallway look as though it is uneven making the tiles appear to slope away into a dip.

The illusion only works in one direction, so you will be perfectly safe on the way out.

Many visual illusions have already been used to try and slow down traffic like this 3D-painted zebra crossing trialed in Iceland that provides an illusory effect of white blocks floating over the road.
