25 Optical Illusions That Will Trick Even The Best Eyes

Josephine Thompson

Dassault Mirage is a series of well-exported French fighter jets. They're not really new, but they were really popular. And, like many things in this world, the series was named after one of the most famous optical illusions: the mirage! If you're an old-timey cartoon character in a desert, a mirage would appear as an oasis and you'd look like real idiot while trying to swim in the water that just isn't there.

Unfortunately, we can't use internet for luring you into such amazing/life threatening illusions. However, there are some benign ones that work online as well as they do on a sheet of paper. So gaze on and be amazed by what tricks simple flat surfaces can pull on you!
