A professional street painter, Tracy Lee Stum, best known for her 3D street paintings, also called anamorphic or pavement chalk art.
“3D Anamorphic Street Paintings are illusionary 2-dimensional images that appear to become 3-dimensional when viewed from a fixed point through a camera lens. Tracy has been creating these types of chalk art images since she first started street painting and continues to challenge herself through this manner of visual expression.”

Even though most of  the optical illusions may look exactly the same, I never posted the exact same image twice (except unknowingly). For those of you who still don’t get what so special about the picture below, well it’s just that all of the lines in it are perfectly straight and parallel to each other. I think this is one of the best examples to show the  Bent Effect. Agree?

The Orbison illusion is an optical illusion that was first described by the psychologist William Orbison in 1939. The bounding rectangle and inner square both appear distorted in the presence of the radiating lines.

The background gives us the impression there is some sort of perspective. As a result, our brain sees the shape distorted. This is a variant of the Hering and Wundt illusions.

If you’ve been following optical illusions sites the photo below may look somehow familiar to you , “The Terrace” optical illusion , successful variations of Sandro Del Prete’s “Folded Chessboard”. If you browse the web, and search for Chessboard Illusions you will find dozen of examples. The Terrace was David Mcdonald’s first published illusion. It proved very popular in the last few years, and it can be found all over the web now. The most interesting part is that when compiling “The Terrace”, David took more than sixty purpose taken photographs, and used them to create this image you see on your left. I’m looking forward to hear you thoughts, and be sure to explain which of the three optical illusions posted today you find the best.

This is a reversal efect of the Zollner illusion or acute-angle contraction.
