My Letter From Oliver Sacks by David Friedman [The Morning New]
In 2002, David Friedman thought of a question he wanted to ask Oliver Sacks, on the topic of 3D glasses and “pseudoscopic” vision. A week after he sent the letter, he received a typewritten reply, complete with diagrams.
African sci-fi features all manner of weird and outlandish things, from crime-fighting robots to technological dystopias. But could they be closer to predicting the future than they realise?
Google Photos recognizes the content of images by training neural networks. Google Research is conducting experiments on these simulated visual brains by evolving images to hyperstimulate them, creating machine hallucinations - like that image of melting squirrels that's been going around lately.

“One night we were eating spaghetti and meatballs and it fell out and rolled across the kitchen table. You said, ‘Dad, your eye popped out’ and kept on eating. I’ll never forget it. You must have been seven or eight. He felt so bad about that—for your sake.”
“I don’t think it bothered me,” I say.

Deep Visual-Semantic Alignments for Generating Image Descriptions. A model that generates free-form natural language descriptions of image regions. Holy crap.
Human tetrachromacy is the purely theoretical notion that a woman might, through a rare mutation on one of her two X chromosomes, end up having four different types of cones in her retina instead of the usual three, and therefore be uncannily sensitive to differences in color. But nobody's ever proven that this phenomenon exists in the real world-- Wait. They found one? (And nobody told me?!) Meet Concetta Antico, the tetrachromat painter. Her personal website is a bit self-congratulatory, but the science appears to be sound. It turns out Antico is not the first, either. A doctor known only as cDa29 was confirmed to have four-dimensional color vision back in 2010. [more inside]

Late in 2013, Guillermo del Toro released a voluminous book, entitled Cabinet of Curiosities: My Notebooks, Collections, and Other Obsessions. As he explains in the video, the 256-page hardcover is a selection from his notebooks, where the director developed many of the monstrosities we’ve seen on screen. The Guardian notes that there’s something of da Vinci’s notebooks in del Toro’s records: the small, neat script, mixed in with the wonderfully detailed sketches, combine to give the impression of del Toro doing his best to record the torrent of his imagination before the thoughts disappear. In this post, we include a number of these images.Previously [more inside]

At the core of good science and engineering is the careful and respectful treatment of data. We calibrate our instruments, scrutinize the algorithms we use to process the data, and study the behavior of the models we use to interpret the data or simulate the phenomena we may be observing. Surprisingly, this careful treatment of data often breaks down when we visualize our data.

Into the Light
Humanity has paused on Jones Street near the summit of Russian Hill in San Francisco. Tourists, businessmen, café workers, the homeless – all seem to have taken a collective breather at this steepest of places, a city peak where stairs are carved into the sidewalks so people don't topple. Only one person keeps climbing, and he's talking, too; he's saying that you can't stop here, that if you just keep pushing, you'll see things no one else will see, that Macondray Lane is just over the hill and that it's the most magical place in all of San Francisco, but you'll never see it if you don't keep pushing, you'll never see Macondray Lane unless you really know how to look.[via Slate]
io9: 'Everyone's A Sellout'
But the "selling out" thing isn't about whether the work is any good, so much as the question of "artistic integrity." Which assumes a simple model in which the artist has a "vision," that forms perfectly in her head, and she then executes that vision with perfect precision — unless she pauses to think about how best to attract an audience of paying customers, in which case the vision becomes compromised and, I guess, blurry. That business, of having a vision and executing it, describes none of the actual process of creating something from scratch, unless you're some kind of minimalist who writes a six-word story or just paints a big dot on a canvas.[more inside]

Four years ago, we showed English language speakers random colors and asked for the color names. Four years later, with CrowdFlower contributors now in every country of the world, the experiment becomes much richer.
Late in life, Claude Monet had surgery to remove the lens of his left eye as a remedy for cataracts, and found that as the lens was no longer blocking them, he could now see ultraviolet light.* When Alek Komarnitsky, engineer and self professed geek, had the natural lens replaced in one of his eyes due to cataracts, he found that he, too could see UV. Naturally, he decided to test the limits of his newfound ability, and to show others what it's like to have ultraviolet vision.(*via Kottke)

"The observers of this unusual visual stimulus reported seeing the borders between the stripes gradually disappear, and the colors seem to flood into each other. Amazingly, the image seemed to override their eyes' opponency mechanism, and they said they perceived colors they'd never seen before."

Visual puns combine two or more symbols (picture and/or text) to form a new meaning. The viewer must mentally elaborate on the visual stimulus to interpret the message. There are lots of examples, some good, some goofy, some bad.
Sea urchins do not have eyes, yet appear to be able to see where they are going. One posible answer: they may use the entire surface of their bodies as a compound eye.

About 8% of the male population has some sort of color vision deficiency. The color blind are unable to clearly distinguish different colors of the spectrum, they tend to see colors in a limited range of hues. Because of this, the color blind have trouble with a lot of websites. The patterns and examples on We Are Color Blind help developers create websites the color deficient can use with minimal problems. Take a color vision test to see where you stand. 50 facts about color blindness.

Wearers of Adaptive Eyewear can make their own prescriptions. The lenses are plastic bladders that change shape and corrective power with a small syringe. So far 30,000 people who may never be reached by an optician or afford conventional eyeglasses now have corrected vision. Recipients are now able to read, mend fishing nets, sew, and perform other tasks requiring good eyesight. The inventor, Oxford University professor Josh Silver, hopes his nonprofit organization can begin manufacturing and distributing up to 100 million pairs a year.
