Phonautograph: A Voice-Carved Memory Wall

A house that listens: Phonautograph turns a spoken knock into a trace you can replay, archive, and print. Phonautograph is a personal site that keeps voices as marks instead of transcripts. Visitors knock by voice, watch a live stylus carve the trace into soot, replay it in Cinema or Bloom, export it as a poster, or preserve it on the wall. I built it on Zo Computer with live audio capture, replay states, PDF export, archive browsing, API stats, and an evening automation that updates the House Almanac and social post.
