This latest version of Mikal Hart’s original reverse geocache puzzle–a box that only opens in one location on the Earth’s surface–is by Markus. At just 3.75″ on its longest side, Markus’s box is by far the most compact and elegant version of the puzzle I have ever seen. [via Hack a Day]
These glueless interlocking table bases based on burr puzzles are from Bulgarian architect Petar Zaharinov. I discovered them while perusing last year’s entries to the Nob Yoshigahara Puzzle Design Competition.
Turns out that the most useless machine (how-to coming up in MAKE Vol. 23) also makes a great cat toy! This Japanese version is sold as a bank that grabs a coin when you place it in the “bowl switch,” which is triggered by the cat in this video. [via Cute Overload]

It is, reportedly, a very rewarding if time-consuming process. You can download the pattern here.
A clever and inexpensive product from indie laser-cutter Evolution Laser Works.
