By Permutting the triangular pieces an egg disappears. How does it happen?

My cousin sent me our newest exhibit. We had some egg illusions in the past, but have to admit they were pretty lame. Well, I hope our newest one brings a change to this lousy tradition. In its core, this optical illusion is very similar to the famous Missing Part test. Additionally, it may remind [...]

Have you seen this advertisement by language school named Berlitz? Apparently, with their help, learning Chinese becomes more than easy! Look at the poster below. This ten-second course for example, already gave you enough knowledge to read the Chinese street signs. Subtlety is great, and it sure conveys the message. Another example can be found [...]

Optical illusion tests were always my favorite! If you remember, few years ago, when this site only started, we posted our original blindness test. Most of you had no problem seeing the “hidden” numbers, but there were few among us that were color blind, and could in no way see the blended symbols. Color blindness [...]

Sorry for no updates yesterday. Still in rush and figuring which apartment to rent, so hope you’ll forgive. About today’s Poggendorf illusion - it is one of the most famous distortion illusions known.

Hehe, just to clear some things - I live in Croatia so the law probably differs in your country. Now that we made this clear, I’d like to ask you if you recognize the mysterious symbols below? No, its not Japanese again. If you concentrate enough, you’ll manage to translate the following symbol-constructed message our [...]
