Behind the Scenes at the National Museum of Mathematics Meta-Logo
The National Museum of Mathematics, which opened in Manhattan in December, doesn't have a logo. It has an infinite family of logos. And the logos the museum uses for official business are not created by design professionals. They're designed by the museum's visitors. The logo is itself an exhibit in the museum.
The museum's unique meta-logo was conceived and implemented at Wolfram Research. When I say "implemented," I don't mean just "calculated" or "rendered," but actually "programmed." This is a logo that requires an implementation.
