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.

7 Historic European Castles Virtually Rebuilt Before Your Very Eyes

While some centuries-old castles are still standing tall, others haven’t withstood the ravages of time, war, or natural disaster quite as well. To give you an idea of what once was, Australia-based insurance company Budget Direct has digitally reconstructed seven of them for its blog, Simply Savvy.

Watch below as ruins across Europe transform back into the formidable forts and turreted castles they used to be, courtesy of a little modern-day magic we call GIF technology.

1. Samobor Castle // Samobor, Croatia

The only remaining piece of the 13th-century castle built by Bohemia’s King Ottokar II is the base of the guard tower—the rest of the ruins are from an expansion that happened about 300 years later. It’s just a 10-minute walk from the Croatian city of Samobor, which bought the property in 1902.

2. Château Gaillard // Les Andelys, France

King Richard I of England built Château Gaillard in just two years during the late 12th century as a fortress to protect the Duchy of Normandy, which belonged to England at the time, from French invasion. It didn’t last very long—France’s King Philip II captured it six years later.

3. Dunnottar Castle // Stonehaven, Scotland

Dunnottar Castle overlooks the North Sea and is perhaps best known as the fortress that William Wallace (portrayed by Mel Gibson in 1995’s Braveheart) and Scottish forces won back from English occupation in 1297. Later, it became the place where the Scottish monarchy stored their crown jewels, which were smuggled to safety when Oliver Cromwell invaded during the 17th century.

4. Menlo Castle // Galway City, Ireland

This ivy-covered Irish castle was built during the 16th century and all but destroyed in a fire in 1910. For those few centuries, it was home to the Blake family, English nobles who owned property all over the region.

5. Olsztyn Castle // Olsztyn, Poland

The earliest known mention of Olsztyn Castle was in 1306, so we know it was constructed some time before then and expanded later that century by King Casimir III of Poland. It was severely damaged during wars with Sweden in the 17th and 18th centuries, but its highest tower—once a prison—still stands.

6. Spiš Castle // Spišské Podhradie, Slovakia

Slovakia’s massive Spiš Castle was built in the 12th century to mark the boundary of the Hungarian kingdom and fell to ruin after a fire in 1780. However, 20th-century restoration efforts helped fortify the remaining rooms, and it was even used as a filming location for parts of 1996’s DragonHeart.

7. Poenari Castle // Valachia, Romania

This 13th-century Romanian castle boasts one previous resident of some celebrity: Vlad the Impaler, or Vlad Dracula, who may have been an early influence for Bram Stoker’s vampire, Dracula. It also boasts a staggering 1480 stone steps, which you can still climb today.

The Smart Reason IKEA Mugs Come With a Chip on the Bottom

This IKEA mug has a low-key design element that might make your day a little easier.

IKEA might be best known for its array of ready-to-assemble furniture like beds, bookshelves, and desks, as well as the wafting scent of Swedish meatballs. But the popular household goods franchise also sells a steady number of coffee mugs. Most are unremarkable, including the spectacularly named VARDAGEN, and therefore never go out of style. But the VARDAGEN does have one odd feature. The 3.25-inch off-white stoneware mug comes with a chip on the bottom. Why?

According to Reader’s Digest, the chip has an official IKEA term: It’s called a drainage gate, and it has a very specific purpose.

The drainage gate was implemented so water wouldn’t collect on the bottom of the mug in a dishwasher. Since mugs are loaded upside-down, water has a tendency to pool on the bottom, which could conceivably result in a slightly splashy mess when unloading.

Because the “chip” is so smooth and uniform, it’s unlikely too many people mistake it for a damaged product. You can also find the drainage gate in the VARDAGEN teacup and saucer set.
