Pixel Tug-of-War Arm Battle on a Wearable 8×32 LED & Touch Sleeve
Two players mash Pad 1 (elbow) against Pad 5 (wrist) as fast as they can while a glowing center rope is dragged across all 32 columns of the 8×32 RGB LED matrix — first to pull the knot past the opponent’s end wins on your washable $199 sleeve.
- A real-mash duel: Each player hammers their own end pad while a glowing knot slides one pixel per hit across the full 32-column rope.
- Instant loser feedback: The losing side visibly shrinks in real time, so nobody argues about the five-second mash.
- Ships as 1 of 50 modes: Pre-loaded as Mash Tug Of War 2P; change match length in the Sleeve Studio app.

Why a Phone Screen Can't Run a Physical Mash Battle Between Two People
- A phone can’t run this: Two people tapping one tiny touchscreen gives no tactile feedback for a frantic mash.
- Two-player by design: Pad 1 is one player’s end and Pad 5 is the other’s, so the sleeve is the whole arcade cabinet.
- Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.

Frequently Asked Questions
- Is there a speed advantage if one player mashing uses two fingers?
- No. Each pad averages taps over a 1-second window and caps the pull rate at 12 px per second, so only sustained honest mashing wins rather than a lucky flurry.
- Can the tug-of-war run without a second person nearby?
- Yes. Pad 1 and Pad 5 can both be hit by one player alternating hands against a short practice AI, useful for solo timing drills.
- How do I change the match length or win margin?
- Open the Sleeve Studio app, edit the match length or win margin in plain English, and send it over Bluetooth.
