The Penrose Triangle was first created by Oscar Reutersvärd in 1934. Mathematician Roger Penrose popularised it in the 1950s, describing it as "impossibility in its purest form". (Source)

It looks like a distant mountain on the other side of a lake, but it's actually just a cloud - below which is clear sky. Incredible image!

No, those dots aren't moving, they're merely changing color.

Maybe The Best Illusion Ever

This is very cool!

If you allow your eyes to follow the movement of the rotating blank dot, the other dots will remain only one color - pink.

However if you stare at the black “+” in the center, the moving dot turns green.

Now, concentrate on the black “+” in the center of the picture for about ten seconds or so, but continue to stay focused. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.

It’s amazing how our brain works. There never was a green dot, and the pink ones don’t ever disappear in reality. Proof enough that we don’t always see what we think we see!
