Roll, the Digital Disposable Camera for Events

Field notes

A host creates a film, prints one QR code, and places it where guests can scan it. The guest camera runs in a browser, saves captures when offline, and sends them once a connection returns; the page says the reveal arrives at 9 AM the following morning. Optional additions include sporadic prompts and one 10–30 second voice note per guest, with example film sizes ranging from 10 guests and 12 frames to 200 guests and 30 frames.
