Tenyo is a Japanese magic trick company that's been around since 1960. They are well known for making clever props. (My friend Richard Kaufman, who often writes for Boing Boing, wrote a 1,400-page two-volume set about the company, called Tenyoism)
Here's a Tenyo puzzle trick called The Perpetual Puzzle (It's available on Amazon). You start by showing a rectangle made from 5 pieces. The rectangle fits snugly in a black plastic frame. Next, you show a sixth piece and combine it to the other five to make a larger rectangle. This rectangle also fits perfectly inside the frame. Finally, you show an even larger seventh piece, add it to the other six to form a rectangle. It, too, fits into the frame. How is it done? (If you know, please don't reveal the secret in the comments.)

Mathematician, artist, and engineer George W. Hart of “Möbius strip bagel” fame has recently been playing with a laser cutter to create head-spinning warped-grid jigsaw puzzles. He came up with an algorithm to generate the initial patterns but “the real fun is step 2,” he says, “using a geometric transformation to warp things.”

While all the downsides of stay-at-home orders and social distancing are evident, there are at least a few small silver linings to come out of all this. For many, this time spent indoors has meant a happy reintroduction to your very own kitchen. You know your kitchen. It’s usually the place that holds all your […]
Have you ever had more time to hone in on fine details than right now? Sure, at first glance, this might not seem like the time to get tripped up on the nitty-gritty of minutia. But how often are you ever going to have this much time to really stop and think about hows and […]
There are plenty of productive ways to spend time while stuck indoors. While it’s undoubtedly fun to binge all 15 seasons of Supernatural or sink days of playtime into an Overwatch campaign, learning something new is definitely a more meaningful and long-term beneficial use of open hours. And if you’re going to invest time in […]
