Information amount

The café wall illusion differs from the Münsterberg illusion in an important way. In the Münsterberg figure the black horizontal borders are isoluminant with the black regions. In the café wall illusion, the rows of tiles are separated by a thin line of mortar (or grout), which, for greatest effect, should be midway in luminance between the luminances of the black and white (or blue and yellow) tiles. The illusory effect obtained is that of a tilt to the mortar lines, with alternate mortar lines being tilted in opposite directions. The width of the mortar lines also affects the strength of the illusion. The strongest effect occurs when the mortar is narrow. In contrast with many other types of distortion illusions, the café wall illusion occurs very early on in the visual system, when the position of edges and brightness differences are encoded. This type of processing occurs prior to the cognitive processes of object recognition. Illusions that involve higher cognitive processes are not likely to be affected by stimulus changes that do not alter the informational content of the picture or object.

and usually there is a text next to the image with small fonts trying

to explain what is on the left, maybe accompanied with arrows.

This really helps to make sure that nobody will get the point :-)

as here there is still some space so we can

place again some small font text. Of

course also with arrows through the

figure

Many images, videos, online demonstrations

Always reference the image

Videos in loop (no stop)

Don’t copy&paste graphics from paper

Avoid scanning images

Check environment if information is visible

Rule of thumb (+2 levels of brightness and contrast)
