A single-page casino slot machine that sends the visitor to a random paper from a curated set of Yohan Jo (HOLI) Lab publications.

Made to live behind a QR code (e.g. printed on a t-shirt for a conference): scan it → pull the lever → win a paper.

• index.html is fully self-contained — no network needed to pick a paper, so it works even on flaky conference Wi-Fi.
• The visitor taps the lever (or anywhere on the cabinet); the title reel and three symbol reels spin and land on a random paper, with a JACKPOT flash, confetti, and a short Web-Audio jingle.
• After landing it shows the paper title, a glowing OPEN PAPER → button, and a 3-second auto-redirect to that paper's link.

The set is hardcoded in the PAPERS array near the top of the <script> in index.html (11 papers as of this writing). To add/remove/replace a paper, edit that array — each entry is {t: "Title", u: "https://link"}. The reel and symbol counts adapt automatically.

Note: unlike the earlier version, this page no longer live-fetches the whole publication list — it only shows the curated PAPERS.

• ?stay — spin and land, but don't auto-redirect (shows the choice).
• ?demo — auto-pull the lever on load (no tap needed).

These can be combined: index.html?demo&stay.
