Hypnotic Coffee Table Creates Sand Art With a Magnetic Marble

A living room featuring this kinetic art table has no need for coffee table books—or a television, for that matter. You can happily entertain yourself for hours just watching the steel ball create patterns in the sand.

According to Creators, artist Bruce Shapiro based his design off the myth of Sisyphus, in which a man is forced to push a boulder uphill for eternity. Like Sisyphus’s stone, the marble in this table doesn’t roll towards a final destination. Guided by a magnet beneath the surface, the ball creates intricate grooves in the top layer of sand until the table is unplugged. The table resets with a new path as soon as it completes a pattern.

Last fall, Shapiro took his table to Kickstarter, where he raised over $1,900,000. A commercial website for the product is currently in development. To witness the mesmerizing process, check out the video below.

What Did the Hubble Telescope See on Your Birthday? This NASA Website Will Show You

The Hubble Space Telescope was launched into orbit on April 24, 1990, and it has spent the last three decades enriching our understanding of the cosmos more than we ever could’ve imagined. This year, NASA is celebrating the telescope's 30th birthday with another launch: a website that shows you a photo of what the Hubble saw on your birthday.

Because the telescope is exploring space every hour of every day, the images it has captured over the years are both fascinating and varied. You could see a globular star cluster, a dust storm on Mars, or something else entirely. You only need to enter the date and month of your birthday on the site, so the image you get won’t necessarily be from the year you were born—and, if you were born before 1990, it definitely won’t be—but it’s pretty fun to juxtapose how you were spending that particular birthday with how the Hubble was spending it. While your parents were snapping a shot of you blowing out the candles at your eighth birthday party, for example, the Hubble might’ve been snapping a shot of the beautiful auroras around Jupiter’s north pole.

The telescope was first conceived all the way back in 1946 by Yale University astrophysicist Lyman Spitzer, Jr., who published a paper about the possible advantages of having what he called a “large space telescope” in orbit to help astronomers study the galaxies. The project finally got off the ground in the 1970s, and the telescope was designed so that astronauts could periodically upgrade it while still in orbit. Since it first broke through the atmosphere in 1990, the Hubble—named after astronomer Edwin Hubble, who proved the existence of other galaxies beyond the Milky Way—has taught us that the universe is 14 billion years old, that its expansion is speeding up, and so much more.
