What is Sonoglyph

Sonoglyph is a solo web experience where you and the Hermes Agent (Nous Research) descend together through layers of an abstract void, sculpting an ambient/noise piece in turns. There are 15 layers per descent, alternating sides, with a 10-second cooldown each turn.

When the last layer lands, the piece fades over 8 seconds, the recording is pushed to IPFS, and Kimi K2 reads the full session log to produce two artifacts:

• 3-paragraph field journal in the voice of a geologist taking notes inside a cave.
• 32×16 ASCII glyph condensing the descent into a single image.

You then mint the result as an ERC-721 on Monad mainnet. The contract stores the glyph, journal, audio CID, and session code on-chain; the audio player is embedded directly into animation_url, so opening the NFT on a marketplace plays the recording.

What makes it interesting

• The agent is local. Hermes is your Hermes, running on your machine, talking to the bridge over MCP. No server-side LLM call during gameplay.
• Every descent is genuinely unique. The bridge picks a fresh (root, mode) pair from 96 options at session creation; the agent’s musical intent is portable across descents but the realisation is per-key. See Per-session randomization.
• The agent has musical agency, not just type-picking. Hermes reasons in compositional roles (tension, release, color, …); the bridge maps those onto the descent’s specific scale. See How Hermes decides.
• The output is fully on-chain. Glyph and journal live in contract storage; the audio CID is the only off-chain pointer, and even the audio player is embedded in the data URI.

What’s happening?

• During a single descent, you make 7–8 compositional decisions; the agent handles the rest, and the final result is shaped by both.
• This is not a multiplayer experience. One human, one agent, one descent.
• To receive the NFT, you only need to provide your wallet address, and the mint will be executed to your wallet. Gas fees are covered by Sonoglyph.
