cd beemon && npm install && node server.js --demo   # fake event feed
python3 -m http.server 8000 -d static               # in another terminal
open http://localhost:8000

Credits

A fork of Listen to Wikipedia by Stephen LaPorte and Mahmoud Hashemi of Hatnote, which is in turn inspired by Maximillian Laumeister's BitListen. The active ka-ching (static/sounds/register/register1.*) is the public domain SoundBible/Wikimedia Commons recording, trimmed to just the primary cha-ching (cut at 1.1s, before the drawer-slam at 1.36s). Alternates live alongside it — point the register Howl in static/index.html at one to swap:

• register-realistic.* — the same recording, untrimmed
• register-fsm.* — produced cha-ching, CC0, from free-stock-music.com
• register-antique.* — antique register cha-ching, CC0, from Freesound #351304
• register-synth.* — synthesized by tools/kaching.py (tweak and re-run to taste)

Audition them all with, e.g., afplay static/sounds/register/register1.mp3.
