Can you guess which nun is bigger?
Here’s a nice submission. This one was sent in by John Newman, who has seen this type of illusion hundreds of times around the net, but never in real life!
Remember when doing our duty, most of the time we let our thoughts slip by, and before you know it – illusions start appearing in front of our eyes! The thing is… do you see all those gray spots appearing at the white intersections below? They aren’t really there (just so that you know)…
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.
Someone sent me this image to the optical illusions blog. Look at the picture on your left. What do you see? There must be something strange going on here. No way that the arch shown here has the proper top. Or can it? I wouldn’t want to ruin your solving experience before you’re ready to see the answer.
A friend sent me our newest exhibit. We had some egg illusions in the past, but have to admit this is different. In its core, this optical illusion is very similar to the famous Missing Part test. Additionally, it may remind you of those missing China men, extra Leprechauns, Mad Scientist soccer team… you know what I mean. To make you understand what is going on around here, let me explain first. In the first card (A) we have one chicken and 8 eggs. Cut this card in 4 pieces (like outlined below), and then again assemble it in a different matter (card B), resulting with proper rectangular image. You will get our original chicken, but the number of eggs this time is different. Additionally, there is a missing piece in this newly assembled card. Why is that? If the surface of both puzzle cards is equal, how can one be missing a piece? Hint: are the surfaces really equal? You tell me! Remember, there is more than one optical illusion present here.

Original “Elephant Illusion“ is one of the most popular and oldest illusions that has been circulating the net. I saw it for the first time 20 years ago or so, but am not sure who the original author for this one is.
