Is it a chalice or two human faces?While some people only see one object over the other, trying to focus on one is an all around struggle in and of itself.

Move the image back and forth.Looking too long at this one might induce horrible headaches. Stare responsibly.

Wavy Shapes While it might look like the shapes are crooked and in every direction, all of the edges are perfectly straight, vertical, horizontal, or at a 45-degree angle.

Moving Circles Stare long enough and it’ll look like the circles are moving.

Crooked Red Lines-The red lines look crooked but then they don’t. Stop messing with our heads

Black Tops, Black Bottoms-We’re pretty sure the black is on top of several pillars…wait.

Optical Fork-This one is similar to the one we showed a little earlier except now there’s a bizarre, optical fork to throw us off even more

Yellow Lines are the same length

Moving Circles-Stare at the black dot and move your head back and forth. It’ll look like the circles are moving.

Moving Squiggles- This psychedelic picture might look like part of it is moving in the periphery of your eye.

Grey Bar- While it might seem like the grey bar in the middle changes shade, it’s actually the same shade throughout. The only shade that changes is in the background.

Black Shades- We’re thinking the point of this one is to make us sick to our stomachs.

Wavy Leaves-No, that’s not a GIF. Stare straight in the middle and the wavy leaves should slow down or stop moving entirely. -

Triangles and Lines- Those lines might look crooked but, of course, they’re actually totally horizontal.

Cow-It took us a while to figure this one out but after a second it finally clicked. Can you see the cow?

Sinking Floor- It might look like the floor is sinking in the middle, but all the squares are the same shape. The dots create the illusion.

Old Lady or Young Woman-Here’s a classic optical illusion that messes with perspective. Some people see an old lady in this picture, and others see a young lady. Can you spot both?

Dark Spots- This optical illusion looks like black spots appear at the intersections of the white lines.

Green Vortex-Whoa. It’s like we’re spinning into the quantum zone with Doctor Strange. This optical illusion should look like the vortex is moving.

Spinning Circles-Here’s a different and totally mind-bending variation of moving circles.

Poggendorf Illusion-The key to the Poggendorf Illusion is the position of the black line. Looking at the left picture, it looks like the black line has shifted a little, but according to the right picture, that isn’t the case.

Blue Flowers-Stare long enough at these blue flowers and a few should spin and move.

Orbison Illusion-In the Orbison Illusion, the red diamond over the radial lines should look distorted.

The further you move back from this optical illusion, the more you’ll be able to see within the picture.Move back from the screen-
