How many faces are hidden in this picture?

This is a picture of Albert Einstein, right? Squint your eyes and/or move away from your monitor and do you see anything different?

Both these photos are identical but the one on the right appears to lean more.

Remember that picture? You know, the one that you thought looked like something else and then you realised it was just a lamp? Well, maybe you were right the first time!

This is an amazing animation by Javan Ivey created by cutting out hundreds of paper stencils and then layering them on top of each other and… well, just watch and you’ll see.
Here’s another great animation of a hypercube found at harvard.edu.

Here’s another take on the rotating snake illusion, this time as cogs.
