(via Codex Silenda: The Book of Puzzles by Brady Whitney — Kickstarter)

This project tickles all of my pleasure spots. A book, that is a puzzle, that can be had as either a ready-to-assemble kit or as ready-to-laser-etch files (all the finished ones are spoken-for), that is under a Creative Commons license as well as a patent, that is crowdfunded. It is a kind of singularity.
