Some optical illusion GIFs that I found to be pretty amazing. You may not ALWAYS believe what your eyes are telling you!
This one actually hurts my brain, but is still really cool!
Stare At The Middle For A Change In Color
Move your eyes above this line and the black and white dots will look like they’re rotating clockwise.
But focus on the central red or yellow dots and the outer ones reverse to show their true direction – counter-clockwise.
These still images start moving once a grating is passed over them.
Look, even this cat sees it.
This is a Penrose triangle, also known as the impossible triangle because how does it work?!
Look at any two sides and it appears to be normal, but the third never quite seems right.
Cats or birds?
Which way is this train going?
This is a variation on the classic spinning dancer illusion.
Look at this black dot and see the outlines filled in with color.
Last, but not least…These yellow and blue blocks look like they’re stepping alternately over the stripes.
But in fact they are always parallel, as you can see when the stripes disappear.
