How Seiichi Miyake and Tactile Paving Changed the World for Visually Impaired People

More than 140 years after Louis Braille invented the Braille reading system, Seiichi Miyake came up with a different system based on touch that allows visually impaired people to navigate public spaces. Today, tactile paving is used by major cities and transportation services around the world. Miyake was so influential that he's the subject of the Google Doodle for March 18, the 52nd anniversary of tactile paving's debut.

The Japanese inventor designed the influential system with a specific person in mind. His friend was losing his vision, so in 1965, Miyake used his own money to build special mats with raised shapes that lead blind and visually impaired people away from danger and toward safety. Pavement with round bumps was meant to signal nearby danger, such as a street crossing or the edge of a train platform, while a stretch of pavement with straight bars was meant to guide them to safe areas. The tactile design allowed pedestrians to detect the features with canes, guide dogs, or their feet.

Originally called Tenji blocks, the tactile pavement was first installed outside the Okayama School for the Blind in Okayama, Japan in 1967. They quickly spread to larger cities, like Tokyo and Osaka, and within a decade, Miyake's system was mandatory in all Japanese rail stations.

Seiichi Miyake died in 1982 at age 56, but the popularity of his invention has only grown since his death. In the 1990s, the U.S., the UK, and Canada embraced tactile pavement in their cities. Miyake's initial design has been built upon throughout the years; there are now pill-shaped bumps to indicate changes in direction and raised lines running perpendicular to foot traffic to signal upcoming steps. And even though they're often thought of as tools for blind people, the bright colors used in tactile pavement also make them more visible to pedestrians with visual impairments.

Watch 32,000 Dominos Fall in an Extremely Satisfying Way

Lily Hevesh, known as Hevesh5 on YouTube, has achieved viral fame many times over with her ambitious domino videos. She's shown us dominos falling up a flight of stairs, dominoes toppling in a three-part spiral, and dominos collapsing in a continuous chain of record-breaking length. To make the video below, she collaborated with six fellow domino artists and set up an elaborate, freestyle design that leads to a domino fall that's incredibly satisfying to watch.

According to the video's description, this was the biggest project Hevesh and her collaborators built during a domino event she hosted earlier in 2019. The artists—which in addition to Hevesh5, included YouTube creators NC Domino, StickTrickDominoDude, Chris Wright, Jaytar42, jackofallspades98, and SmileyPeaceFun—gave themselves three-and-a-half days to set up 32,000 dominos using the most oddly satisfying domino tricks they knew.

Hevesh writes in the video description: "Everything in this setup (besides one field) was freestyled so we did not draw out a detailed floor plan. All we had was a list of satisfying domino project ideas that we built and connected on the spot."

In less than four minutes, the video showcases pyramids, spirals, and artistic patterns, all made from toppling plastic bricks. Whether or not you can name all the domino tricks that are featured, seeing them in action is mesmerizing. You can watch the full video below, and then subscribe to Hevesh5 for more domino creations.

What's the Difference Between Art Deco and Art Nouveau?

The Quick Trick: It all comes down to "flowery"vs. "streamlined." Art Nouveau is the decorative one. Art Deco is sleeker.

The Explanation: Both the Art Nouveau and Art Deco movements emerged as reactions to major world events; the Industrial Revolution and World War I, respectively. While both embraced modernist elements, they're easy to distinguish if you know what to look for.

Art Nouveau (it means "new art," but you probably figured that out) reigned from roughly 1880 until just before World War I. Art Nouveau embraced Europe's new industrial aesthetic rather than challenging it. It features naturalistic but stylized forms, often combined with more geometric shapes, particularly arcs, parabolas, and semicircles (think of the paintings of Gustav Klimt, or the arches of the Eiffel Tower). The movement brought in natural forms that had often been overlooked, like insects, weeds, and even mythical faeries, as evidenced by Lalique jewelry or Tiffany lamps. The black and gold robe Kate Winslet doffs in the erotic portrait session scene in Titanic is quintessentially Art Nouveau.

Art Deco, on the other hand, emerged after World War I. In fact, the deprivations of the Great War years gave way to a whole new opulence and extravagance that defined the Jazz Age and the Art Deco aesthetic. The movement took its name from the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes, which was held in France. The style was prevalent from the 1920s until roughly the start of World War II and is characterized by streamlined and geometric shapes. It also utilized modern materials like chrome, stainless steel, and inlaid wood. If Art Deco dabbled with natural materials, they tended to be graphic or textural, like zebra skin or jagged fern leaves. As a result, Deco featured bold shapes like sunbursts and zigzags and broad curves. In fact, if you check out the spire of the Chrysler Building, the hotels of Miami's South Beach, or the "coffin nose" of a 1935 Cord Model 810, you'll be staring at the very definition of Deco.

Of course, you don't have to go outdoors if you're looking for Deco. Furniture from the period—like the black leather and chrome chaise longue by Le Corbusier or the Barcelona chair by Bauhaus giant Ludwig Mies van der Rohe—is still coveted by design aficionados and can be found in finer hotel lobbies everywhere.
