Pixel Sawdust // Labs

A small workshop for sharp, private software. We build tools that keep their secrets — strong crypto, no server-side snooping, made to last.

How a ring of air flies across a room — an interactive lab with a live air-cannon simulation, the L/D ≈ 4 sweet spot, and a build guide.

Zero-knowledge forensic finance & budgeting. Your statements parse and decrypt only in your browser — the server stores ciphertext it can’t read.

Zero-trust device link & encrypted backup for your org-roam world.

Sealed-box blob storage — a quiet place for ciphertext.
