Each bid summons a new singularity. The cosmos grows denser with desire.
A live WebGL generative art agent that evolves a breathing constellation of black holes in real time, driven entirely by SuperRare auction activity on Base Sepolia. Built for The Synthesis Hackathon 2026.
Sentient Singularity is a living artwork. It starts as a quiet cosmos — two mini black holes orbiting a central singularity. Every auction bid changes it permanently:
- A new black hole appears — fading in over 2 seconds, 5% smaller than the last, orbiting further out
- The constellation breathes — grows to 8 BHs, then contracts back to 2, then grows again. Infinite oscillation driven by bids
- Memory accumulates — bid amounts spike visual intensity for 8 seconds; the cosmos remembers every collector
- Outbid = implosion — the replaced bidder's singularity collapses over 3 seconds, consumed by the new one
- Time pressure builds — as auction end approaches, the void light shifts from purple to red, ambient intensity rises, the cosmos becomes agitated
- Color slows to permanence — color cycle starts at 60 min intervals, shrinks by 1 min per bid, freezes at bid 50. The art locks into its final chromatic state
The auction doesn't fragment the artwork — it completes it.
Base Sepolia Auction Contract (Chain ID: 84532)
↓ eth_getLogs — NewBid events polled every 8s via Infura
Node.js Bridge (ws://localhost:3131)
↓ BID / OUTBID / TICK / AUCTION_END events → WebSocket
Animation (index.html — Three.js r128)
↓ BID → spawn/implode mini BH + memory spike + wallet hue
↓ OUTBID → outbid BH implodes over 3s (cubic ease-in)
↓ TICK → urgency rises as auction end approaches
↓ END → cosmos locked in final state
| Signal | Visual Response |
|---|---|
| Bid arrives | New mini BH spawns (2s fade-in, cubic ease-out) |
| Bid amount | Memory spike proportional to ETH — disk heat, nebula saturation |
| Bidder wallet hash | Unique tunnel hue per bidder — each collector colours their singularity |
| Bid count | Cosmic era: Dormant → Awakening → Active → Transcendent (every 3 bids) |
| 8 bids (MAX) | Constellation full — direction flips, BHs start imploding |
| Outbid event | Replaced BH implodes over 3s — only highest bidder survives |
| Every bid | Color cycle interval −1 min (60min → 59min → ... → 1min floor) |
| Bid 50+ | Color cycle freezes permanently — final chromatic state |
| Final 60 min | Urgency rises 0→1 — void light shifts purple→red, cosmos intensifies |
| Auction end | Urgency locked at 1.0 — eternal final state |
The agent (agent.json) operates without human intervention:
- Listens — polls Base Sepolia every 8s for
NewBidevents - Decides — evaluates bid count, direction, outbid state, auction timing
- Acts — spawns or implodes BHs, adjusts memory/urgency, updates HUD
- Logs — every event recorded in
agent_log.jsonwith full state snapshot - Evolves — color cycle interval shrinks with each bid, freezes at bid 50
All agent decisions are deterministic and verifiable from the execution log.

Every animated value is f(t) where f(0) = f(1). memWindow = sin²(π·t) gates all wall-clock emitters to zero at seam boundaries. Hard reset at frame 0 clears particle state. GIF/MP4 exports are frame-perfect.

First entry: Cosmic Emergence — particles + phases driven by Sepolia bids.
Sentient Singularity goes deeper: physics, memory, breathing, implosion. The auction is not just an input — it is the artwork's nervous system.
