I don't know if this is a human retina melting, a lava well from a volcano near Mordor, or the eye of the devil himself. But what I do know is that the more I watch it, the more hypnotizing, darker, and scarier it gets.
Hiding in the shadows between the colors we see everyday are weird, impossible shades, colors that you shouldn't be able to see and generally don't... unless you know how. Here's a simple guide to seeing impossible and imaginary colors.
Youtuber rasmusab has posted a video that's as adorable as it is thought provoking. In it, a small orange kitten with white feet appears transfixed by an 8.5 x 11 printout of the famous "rotating snakes" illusion (just one variation on the "peripheral drift illusion" — see an example for yourself below). The kitten…
Yes, blood. Blood out the eyes. It's a display that's as impressive as it is shocking — in a last-ditch effort to ward off predators, several species of horned lizards will increase the blood pressure in vessels surrounding their eyes, to the point that they actually rupture, gushing five-foot fountains of…
Swedish artist Sandra "psychosandra" Holmbom pulls off some pretty remarkable optical illusions with makeup, but holy crap does this one take the cake — with an eldritch emphasis on "optical."
I wrote about Visionary Effects awesome—and freaky—animatronics work before. The second version of their robotic eye with dilating pupil is even more impressive and way freakier. Just amazing. I wish I had a pair of these on my living room walls. [Thanks Visionary Effects!]
Eyes. They're the windows to someone's soul. They also look really cool when shot in an extreme close-up. For this week's Shooting Challenge, capture eyes. Well, eye.
Last week, a softball-sized eyeball washed ashore in Florida. At the time, researcher Charles Messing guessed the eye belonged to a swordfish. A day later, Deep Sea News' Craig McClain got in touch with Sönke Johnsen, "an expert on everything visual in marine organisms" (awesome, right?). Johnsen told McClain the…
Holy heck, people. Now that is an eyeball. Beach-walker Gino Covacci encountered the monstrosity yesterday while ambling about the Florida coast, and while scientists have yet to identify the creature from whence it came, the consensus seems to be that whatever it was, it was big.
Yesterday, Gino Covacci was walking peacefully by the sea when he found this: a gigantic, monstrous eye still oozing blood. Scientists haven't identified the leviathan who lost it yet. Was it a giant squid, a whale, or the eye from a titanic monster born mutant because of nuclear tests?
Have you ever wondered what it might be like to be temporarily blind? Of course you have. In fact, there is a way to trick your body into becoming blind, at least for a few minutes.
Electronic implants which restore sight to the blind aren't anything new, but one of their major stumbling blocks has been the need for an external power source. Now, that's about to change, because a team of researchers has built a digital implant out of infrared-slurping photovoltaic pixels—so it can power itself.
It's no secret that putting various colors together makes them look different. Put off-white next to black, and it looks completely bright. But did you know that, with the Munker Illusion, you can make something change color completely, right in front of your eyes?
It's not unusual for optical illusions to create afterimages, ghostly reflections that show up after staring at something too long. This particular afterimage is a bit different. For one thing, it looks nothing like the original image. Also, it moves.
Adanson's jumping spider has eight eyes, but the way they're put together doesn't actually seem that useful for, well, seeing things. These spiders use a previously unknown trick to judge their surrounds and leap great distances...all thanks to blurry vision.
You're the patient? Excellent, please lie down on this table. I'll be your doctor today but will be working from the next room, remotely controlling the needle-wielding robot above you—I'll try not to sneeze! Just kidding. So, who's ready for some eye surgery?
After a close encounter with Death's sickle during a car accident in 2005, Tanya Vlach lost her left eyeball. Not content with any old prosthetic replacement, she wants the Kickstarter community to fund a totally Terminator-style cyborg eyeball.
As cataracts is the main cause for blindness, a phone accessory that diagnoses cataracts could cut down on blindness, particularly in the developing world. As shown in the video here, MIT's CATRA is a low-cost solution which not only detects cataracts, but also tracks the severity of them over time.
There's a reason that certain wavelengths are known as "visible" light, because those are the wavelengths that humans and most animals even remotely like us can see. But one mammal can see in ultraviolet light...and it's all because of snow.
This image of a tartan ribbon is the first-ever permanent color photograph, and it was taken 150 years ago yesterday by the legendary scientist James Clerk Maxwell. So just how did he create colors that would last for over a century and a half?
