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.

Often symbols of MORTALITY (or some romantic notion of immortality – as the belief that a spiritual part of a person survives death) and POWER, skulls have been employed in human rituals and art since the dawn of humanity: from the ancient animal skulls in Paleolithic burial sites, to the curlicued cattle skulls that haunt Georgia O’Keeffe’s canvasses. Skulls cannot be assumed to be only a mere symbol of death, they are also used in initiation rituals as a symbol of REBIRTH, symbolizing the ‘sephirah daath’ (סְפִירָה – sephirah, “enumeration” in Hebrew) on the cabalistic tree of life, the gateway to a higher awareness only achievable through spiritual death and rebirth.
Look at the colored rings from a distance. Then decide which ones have YELLOW inner circles, and which ones have BLUE inner circles.

Take a look at this photo — it almost looks like a “transparent” or “camouflaged” knife! I snapped it years ago at a magician’s party. The trick here is all about specular reflections. It’s a simple illusion, but surprisingly effective. When you place a knife blade between the tines of a fork, it reflects nearby objects, making the blade seem almost invisible.

This table is sturdy and stable. And yes, the chains are ordinary chains. Here is the tutorial that explains how to create such a miracle.

Here is an animated example:

Curiously enough, the cubes don’t move only the background color changes…

Here is my tutorial to create an amazing autokinetic animation.

Look at the picture from a certain distance and check which colors are in the patchwork.
