Gifts for Programmers
Most programmer gifts are punchlines. These are not. Every design here is a real piece of computing — the Enigma’s rotor wiring, the Diffie–Hellman key exchange, a one-time pad — drawn accurately enough that the recipient can check.
If you’re shopping for someone who likes science stuff, robots, and space, and the only spec you have is “the fabric has to be good”: tees print on Bella+Canvas 3001 combed ring-spun cotton, hoodies on Lane Seven French Terry, and we count durability in washes, not adjectives.

The rotor wiring that scrambled a war’s worth of messages, drawn as a chord diagram. The safest pick on this page.

The key exchange that secures the modern web — a generator’s walk through a cyclic group.

A one-time pad, the only cipher proven unbreakable. For the cryptography purist.

Two words that describe every system they have ever debugged.

The Enigma wiring at hoodie scale, on heavyweight Lane Seven French Terry. The bigger gift.

Not found — the cleanest error code, as a quiet cap. No sizing required.

A 16 × 32 inch black desk mat for the focused, distraction-free setup.

The handshake that runs the web, as a weatherproof laptop decal from $3. The stocking filler.
Good to know
Unsure on size? The cap, the desk mat, and the decal don’t have one. Tees follow standard Bella+Canvas sizing and run true.
Everything is printed to order. If anything about the order isn’t right, email care@lunthra.com — a real person answers.
