One of my favorite zines of the early 1990s was Beer Frame: The Journal of Inconspicuous Consumption. In each issue, the author, Paul Lukas, reviewed mundane products by examining their packaging and design details in a way that made me look at everything in the human-made world with fresh eyes. He stopped publishing it a few years later and focused on reviewing sports uniforms for the next 25 years, which held zero interest for me, unfortunately. But a couple of months ago, Lukas rebooted Inconspicuous Consumption as a Substack newsletter. After reading the issue about the superiority of "Beware of Dog" signs over "Beware of the Dog" signs, I immediately bought a subscription. — MF

Henry Segerman is a mathematician who likes to make clever, remarkable mathematical shapes and 3D print them out into real things. He then makes a youtube explaining their origins. Each beautiful object becomes a mathematical lesson. He favors odd gears, weird knots, unusual shapes. You can watch Segerman videos for very nerdy satisfaction, but to fully close the loop, you can also purchase one of his exquisite objects shown in the videos. I have a few on my shelf. They are both conversation pieces and mathematical proofs, and great gifts for the nerds in your life. — KK.

The Voyager Golden Record, included on the 1977 Voyager space missions, is a collection of Earth's sounds, music, and images intended as a message for extraterrestrial intelligence. My friend David Pescovitz won a Grammy for the Voyager Golden Record 3xLP Box Set he co-produced, which includes the original content and an illustrated book. Normally priced at $110, it is currently on sale for $88. — MF
