RoboRoach + Twitter = Crowdsourced cockroach steering


Artist Brittany Ransom has built a tiny cockroach backpack which lets her remote control a cockroach with Twitter. For science art! CNET has a video of the insectoid cyborg:

Ransom let visitors to the Chicago Artists' Coalition's exhibition Life, in some form control the roach by tweeting the hashtags #turnroachleft and #turnroachright at its twitter account, @tweetroach. Every thirty seconds, the winning hashtag was sent as a command to the insect through the RoboRoach control circuit.

Ransom passed on her artist's statement to CNET:

At what point does its intelligence and ability take over? How much does it take before we are all desensitized to overstimulation? As we, as human beings, grow more cyborgian and interconnected through social media, this project helps us participate in discovering the answer.

While Ransom's point is compelling, the real wizardry lies in the RoboRoach gear itself. Created and sold by neuroscience hackers Backyard Brains, the kit lets anyone build cyborg cockroaches at home (some assembly required).

After some minor roach surgery, it sends small electric currents to the roaches antennae, making it think it's running into a wall. Zap the left antennae, and it'll turn right, and vice-versa.

Backyard Brains describe the experiments you can do with the kit:

You can use this experimental model to teach your students about current neurotechnology. For example, 1) How long before the cockroach adapts to the stimulation and learns to ignore it?, and 2) What is the optimal circuit design to make the electronics as simple and light as possible?

It's like a 21st century spin to the idea that cockroaches will survive nuclear war: TwitterRoach will probably learn to adapt to and ignore twitter long before we do. The ultimate survivor indeed.

With everything from iPhones to clothing turning monochrome, is the West afraid of colour?

If modern design appears particularly achromatic, it only reflects the "chromophobia" which courses through the history of Western thought.

To many English observers, 1666 – the year that the poet John Dryden christened the annus mirabilis, or “year of miracles” – wasn’t especially miraculous. The country was gripped by plague and, after a hot, dry summer, the Great Fire cut a swath through London. But for Isaac Newton, then still a student, it did prove illuminating. It was in 1666 that he first used prisms to prove that white light was not a pure, indissoluble substance but was made up of different coloured rays. This was such a profound challenge to the prevailing world-view that even Newton was shaken. “I perswade my self,” he wrote, “that this Assertion above the rest appears Paradoxical, & is with most difficulty admitted.”

The belief that colours are inferior and therefore naturally subordinate, rather than fundamental, was not new in Newton’s day, nor did it end with his discovery of spectral colour. A pattern of chromophobia – an aversion to colours – courses through Western thought.

Writing in the fourth century BC, Aristotle argued: “The most attractive colours would never yield as much pleasure as a definite image without colour.” For Renaissance artists, this idea was defined by the division between disegno, drawing or design, and colore. Disegno was the foundation of any serious artistic endeavour. The preference for achromatic, “intellectual” form is also evident in architecture. Despite rock-solid evidence from the 19th century proving that Greek marble buildings and statues were once brightly painted, the classical ideal has remained anachronistically bleached. And while modernist and postmodern architects have made some use of colour, the primacy of form is unmistakable in the work of everyone from John Pawson to Zaha Hadid and Toyo Ito.

A broad cultural dislike of colour is curious because, speaking in evolutionary terms, our ability to see it has been crucial to our success. Colour vision in primates developed between 38 and 65 million years ago and makes us better able to find ripening red and yellow fruits amid green foliage. Neurons devoted to visual processing occupy much more of our neocortex real estate than those devoted to hearing or touch. Estimates vary but the Optical Society of America has suggested that it may be possible for humans to distinguish between up to ten million different shades.

And we have put this skill to good use. Bold colours have been used by many cultures to mark temporal and spiritual power. Tyrian purple, a rich, reddish dye said to resemble clotted blood, was made using an extract from two different kinds of Mediterranean shellfish and was beloved by emperors in the ancient world. A single pound of dyed cloth would cost a skilled craftsman three years’ wages and became steadily more expensive as the shellfish became rarer.

But even as such saturated colours were coveted, they also elicited disgust. The manufacture of many, including Tyrian purple, involved ingredients such as stale urine and dung. Dye and paintworks were relegated to the urban fringes. Increasingly, the wearing of bright colours was seen as vainglorious and ungodly. Protestants indicated their humility by whitewashing over jewel-coloured murals and smashing stained-glass windows in churches, and by restricting their sartorial palette predominantly to black. An echo prevails today in men’s suits: colours are largely confined to small accessories such as ties and white shirts are held up as the ne plus ultra of refined sophistication. (The late Apple co-founder Steve Jobs went one better, opting for a uniform of identical black turtlenecks.)

One reason for this distrust is that colours are difficult to conceptualise. Do they exist physically, or only in our brains? Does everyone see them the same way? Colours have been maligned as chaotic, fickle, irrational and female. The early Christian thinker St Augustine of Hippo accused them of “a seductive and dangerous sweetness”.

Our ambivalence to colour, however, has profited white. Like black, white has not been classed as a real colour since Newton. It has almost become an anti-colour. Take Apple, for example. Although Sir Jony Ive is usually credited with the company’s love for monochrome products (it was certainly Ive who brought this to its apogee), the trend predates his arrival. It can be traced back to the “Snow White” design language developed in the 1980s. Today, as consumer neophilia demands that technology be continually refreshed, Apple’s higher-end products are available in the smallest range of colours – usually just white, black and, for the Asian market, gold – while those lower down come in a slew of fruity brights.

White is not only big business for Apple. In 2014, a Californian man named Walter Liew was found guilty of 20 counts of economic espionage and sentenced to 15 years in jail for selling the secret to a very special shade of titanium-oxide white, used in everything from luxury cars to tennis courts, to Chinese firms for $28m.

Perhaps the final word on the matter should go to Le Corbusier. In 1925, the great modernist recommended that all interior walls should be whitewashed, to act as a moral and spiritual restorative. But he wasn’t just advocating white for white’s sake: although he continued to dabble with colour, he disapproved of it, too. “Let us leave to the clothes-dyers,” he wrote, “the sensory jubilations of the paint tube.”
