Uniqlo x Akamai T-shirt Hides a Working Bash Easter Egg

Original: Decoding the obfuscated bash script on a Uniqlo t-shirt

Why This Matters

Demonstrates brand engagement through embedded, functional code as a novel physical medium for developer outreach.

A Uniqlo t-shirt designed by Akamai for its Peace for All campaign features an obfuscated bash script printed on the back. When decoded, the base64-encoded string runs a terminal animation displaying a scrolling 'PEACE FOR ALL' message.

A blogger named Tris Sherliker purchased a Uniqlo t-shirt from Akamai's Peace for All campaign after his wife noticed the back featured what appeared to be a shebang line (#!/bin/bash) followed by a large alphanumeric block. The block is a base64-encoded Here string fed to eval via base64 --decode — a technique the author noted is 'basically how people ship viruses.'

Decoding the string required manual OCR, since base64 has no error correction and any transcription error would break the script. Sherliker used Android's built-in circle-to-search OCR, Tesseract, and Claude in parallel, then diffed the outputs to identify mismatches. Once corrected, the decoded script is a fully functional bash program that hides the cursor, traps CTRL+C to restore it, and runs an infinite loop animating the text '♥PEACE FOR ALL' across the terminal using sine-wave positioning.

A second Akamai t-shirt in the same range was found to contain a truncated, non-functional script — its code ends mid-word with 'retu' instead of 'return,' making it unrunnable. The first shirt's script, however, is complete and executes as intended, functioning as a genuine hidden easter egg for technically inclined customers.
