12 Of The Most Awe-Inspiring Optical Illusions From Around The World

You won't believe your eyes, but it's all real. See how Dynamic Perspective on the Amazon Fire Phone lets you tilt, auto-scroll, swivel, and peek to navigate menus and access shortcuts with one hand.

From the German word for "halo," this phenomenon makes it look like there's a halo around the viewer's head when their shadow lands on dewy surfaces like lawns or dry surfaces like the moon.

4. Fata Morgana

Fata Morgana occurs in deserts, in the Antarctic, and out at sea, and is likely the source of the Flying Dutchman myth. Cold air trapped under hot air projects multiple versions of the same image on top of itself so your eyes receive one severely distorted image.

5. Green Flash

This phenomenon is generally clearest at sunset over water, but the effect, similar to Fata Morgana, occurs when the last spectrum of color to reach your eyes through the atmosphere is a burst of green.

6. Phantom Suns

Also known colloquially as sun dogs and scientifically as parhelia, it's not Star Wars predicting our future so much as it is light bending through ice crystals until it looks like our sun has another two suns on either side.

7. Sea Sparkle

When disturbed by particularly rough seas or by crashing waves in parts of the Indian Ocean, some dinoflagellates emit light, making the water look like it's glowing or sparkling.

9. Whiteout

Usually only occurring during winter or at the poles, snow or fog obscures the horizon to the point that nearly everything you can see is white — even if you're a couple feet away from other people and objects.

10. Atmospheric Ghost Lights

Known as many things worldwide including will-o'-the-wisps, foxfire, and hinkypunks, these phenomena usually occur in marshes and bogs, and explanations range from bioluminescent fungi to outright fable.

11. Ball Lightning

For everything from UFOs and WWII's Foo Fighters to supposed spirits and erratically moving skylights, most explanations amount to simple lightning or St. Elmo's fire — natural phenomena that might be atmospherically distorted to appear to be moving faster than possible.

12. Impossible Objects

These are traditionally man-made since they add a third dimension to two-dimensional objects: for example, the triangle sculpture on the left should not be able to twist like that, but the close examination (on the right) proves it truly can't twist like that. Other popular impossible objects include blivets and Penrose stairs.
