Scintillating Starburst: Seeing rays that aren’t there…

This is one of my oldest illusions I created in the 90s. In the picture you may see ghostlike dark radial beams. This illusion is a variant of the Herman’s scintillating grid illusion. I designed this illusion just by turning 45 degrees the Herman grid and then by applying a polar transformation.

From my book “Eye Tricks“, 2001-2007.

A simple real life illusion: the transparent knife!

Have a look at the picture, it looks like a “transparent” or “camouflaged” knife! I took this photo during a magician party many years ago. This illusion is based on specular reflections, it is simple but effective… In fact, when you place the blade of a knife in the middle of the tines of a fork, it will reflect other objects that are nearby.

My dossier on visual illusions

Focus is an Italian monthly popular science magazine published in Milan, Italy, with which I have collaborated for more than 10 years.

Focus Magazine issue #336 featuring my article and my optical illusions has been released on October 2020. It contains my special 10-page dossier on visual perception with over 13 original visual illusions of my creation and their related explanation.

The cover also features a special effect I designed for Focus: as you read the main title, the cover image moves and, curiously enough, the title changes if you look at it closely (ILLUSIONI) or from a distance (COSA VEDI?).
