Is it a B or 13? Depends how you read it...

Don't stare for too long!

This headache inducing illusion is simply a static image of a green background with a series of blue dots, however when you look at it the whole thing appears to move and warp in a wave-like fashion.

Nature is pretty good at these illusions. This furry caterpillar is more than it seems...

Freaky turned up to 11!

All the little squares are the same size!

Just a bunch of black splodges - but look closer and a word will appear.

The squares in this illusion are actually square, though they appear distorted.

The distortions are consistent with how squares in the real world would change their appearance if one were moving forward toward the center point.

Squint and all will become clear!

The 'Evening Dusk' illusion trick you into thinking that it's much brighter in its center, compared to white background surrounding it's outer edges.

But it's not!
