Prototype Poltergeist

An interactive voice museum in The Hallway of Infinite Onboarding, guided by Professor Echo—an AI curator speaking through a custom Hume voice.

Visitors diagnose broken digital exhibits, propose repairs, and earn The Tiny Clipboard of Restraint. Expression signals shape atmosphere only; they never decide success.

The live voice session needs Hume API access and a microphone. While usage limits reset, this preview and the GitHub source document the prototype. A hosted demo link can replace the preview when the voice build is public again.
