This is not what it appears to be.
Just try to focus the best you can on this animation.
This T-Rex's head and eyes seem to follow you wherever you go.
Stare at this image close up for 60 seconds then lean back and close your eyes. You will see an image of Jesus. This one is freaky.
Try to say the color and not the word.
Don't believe it? Try opening up the image in Paint or another image editor and put the 2 tiles side by side.
Here is another one that will make your eyes fall out of your head.
Try this out, and experience natural hallucination. Stare at the center, keep your eyes still & look away when instructed. Don't worry, this isn't one of those lame "something pops up & scares you" videos.
Mind your step is a street illusion in Stockholm created by Erik Johansson. It looks totally awesome and must have taken some serious skills to create.
