Hacker Decodes Hidden Bash Script on Uniqlo T-Shirt, Finds a Love Letter to Linux

A Uniqlo charity shirt designed by Akamai hides a fully functional terminal animation. One blogger's wife spotted it on a rack — and the internet went wild.

A computer science blogger's wife spotted something unusual on a Uniqlo rack this week: a t-shirt with what looked like a wall of random alphanumeric characters on the back. She was right to flag it — the jumble was a fully functional, obfuscated bash script.

Tris Sherliker, an IP and technology lawyer by trade, recognized the telltale shebang line immediately. The code block on the shirt turned out to be a base64-encoded script that, when decoded, produces a continuous terminal animation: the words "PEACE FOR ALL" scrolling in a sine wave with 256-color gradients cycling from cyan to orange.

The shirt is part of Uniqlo's Peace for All charity campaign, designed by Akamai — the content delivery network that helped build the early internet. The light tan color of the shirt itself is a nod to the "beige box" plastic casings that housed early web servers. The heart-in-curly-braces design on the front evokes open-source syntax.

Sherliker had to OCR the text from photos, diffing results from Android's circle-to-search, Tesseract, and Claude to produce a perfect transcription. "I told my wife 'that's basically how people ship viruses' and bought it," he wrote.

The script itself is clean and well-commented, including a Japanese greeting: "おめでとうございます！隠されたサプライズを見つけました！" — roughly, "Congratulations! You found the hidden surprise!" It loops infinitely, drawing the campaign slogan across the terminal until the user hits Ctrl-C.

The post hit the top of Hacker News with over 1,000 points and nearly 200 comments, suggesting the intersection of fashion and open-source code still has the power to surprise.
