Can I load my own truth-or-dare prompts instead of the defaults?

Yes. Open the Sleeve Studio app, type your list of prompts into the decks block in plain English, and send the mode over Bluetooth.

How fair is the spin — can it land on the same segment twice?

Each spin is seeded from the tap timing, so while repeats are possible the result is genuinely random and never biased to a fixed column.

Will the scrolling prompt be readable in a dim living room?

Yes. The 256-pixel diffused matrix is designed for low-light readability, and you can raise brightness per profile in the Sleeve Studio app.

Spin-the-Arm Party Wheel & Truth-or-Dare Ticker on an 8×32 LED Sleeve

Tap Pad 3 at your wrist to spin a decelerating pixel cursor across all 32 columns of the 8×32 RGB LED matrix, freeze it on a segment, and auto-scroll a truth-or-dare prompt down your forearm within the 256-pixel display on the $199 sleeve.

No shuffle, no pause: Pad 3 spins a decelerating cursor across 32 columns, locks a segment, and auto-scrolls a matching truth-or-dare prompt.
Pass the arm, not a phone: The prompt stays on whoever holds the room; 5 sewn fabric pads re-spin and skip with a knuckle mid-round.
Pre-loaded & customizable: Ships as one of 50 built-in modes; load your own truth, dare, and hot-take prompts in the Sleeve Studio app.

Why a Card Deck or Phone App Stalls a House Party

Keeps the momentum: No dog-eared deck to dig out and no thumb passing a phone card-by-card while everyone waits.
Random every spin: The decelerating cursor seeds from the tap timing, so results are never biased toward one segment.
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.

What Each Forearm Pad Does (Pads 1–5)

Pad 1 (Elbow)Single tap — Previous prompt / back one segment on the wheel · LED cue: Cursor steps left one colored segment marker

Pad 2 (Upper Mid)Single tap — Toggle Truth deck vs Dare deck vs Hot Take deck · LED cue: Header label scrolls TRUTH / DARE / HOT TAKE in amber

Pad 3 (Center/Wrist)Single tap — Spin the wheel — cursor decelerates and freezes a segment · LED cue: Full 32-column sweep decays to a stop; segment flashes white

Pad 4 (Lower Mid)Double tap — Re-roll prompt without changing the landed segment · LED cue: Prompt text re-scrolls; segment marker holds its color

Pad 5 (Wrist)Press & hold — Emergency skip / mark prompt as done · LED cue: Matrix flashes green DONE and returns to idle dim
