This '3D' Crosswalk Uses an Optical Illusion to Slow Drivers

Crosswalks are meant to tell drivers to yield to pedestrians, but too often they're treated as a suggestion rather than a rule. If the possibility of hitting someone isn't enough to slow speeding drivers, two artists from Gujarat, India are hoping this sneaky optical illusion will do the trick.

As WIRED reports, Shakuntala Pandya and daughter Saumya Pandya Thakkar have teamed up to redesign the classic white-striped crosswalk to look like roadblocks jutting up from the street. To drivers on the highway in the west Indian city of Ahmedabad, the shapes will look like three-dimensional structures from far away. But the artists say the illusion fades as cars get closer, so it shouldn't lead to any motorists slamming on their breaks to avoid crashing into something that isn't there. 

Highway officials have experimented with similar 3D crosswalks designs here in the states. A few years ago, the Oklahoma Department of Transportation transformed the plain white blocks of one crosswalk by painting brightly colored shapes around them to give them the illusion of being raised from the rest of the street. Parts of Chicago have also featured eye-catching 3D markings since the beginning of the decade. There's still no comprehensive research about whether these designs are actually effective. But in India, a country where traffic-related deaths are on the rise, experimenting with safer road signage can't hurt.

Bremont's New Stephen Hawking Watch Contains Pieces of the Late Scientist's Desk

By the time Stephen Hawking died in 2018, he had left a lasting impact on the worlds of physics and cosmology. If you're looking for a way to remember the famed scientist, now you can wear a watch made from parts of his desk while supporting his field at the same time.

As Esquire Middle East reports, the Bremont Hawking Collection is an elegant homage to the intellectual giant. The watches contain four wooden disks made from his personal desk. The furniture piece was one of Hawking's "most treasured possessions," according to his estate.

In addition to pieces of a real item from his home, the watches are filled with little details that honor the famed theoretical physicist. The dial is engraved with a starscape that mirrors the night sky that was visible over Oxford University the day Hawking was born (January 8, 1942). Real pieces of meteorite embedded in the device further emphasize his devotion to studying space.

Proceeds from the watch will also be used to carry on Hawking's legacy. When you purchase one, part of the cost will be donated to The Stephen Hawking Foundation. The organization supports cosmological research as well as patients of Motor Neurone Disease, the same condition Hawking lived with.

Bremont is producing the watch in limited batches: 388 of the stainless steel watch ($10,588); 88 of the platinum watch ($10,588); 88 of the rose gold watch ($23,833); and 88 of white gold watch ($25,157). The number 88 is a reference to 1988, the year Stephen Hawking's book A Brief History of Time was published.
