The Forgetting Engine — 2026-09-26
What It Is
A poetic entropy-visualization that simulates the experience of watching data dissolve into static. The engine harvests system entropy (PID, time_ns, uid, OS random), seeds a 2D forgetting field, and renders it as ASCII — where memory fragments fade according to diffusion decay rules. What remains are “memory traces”: faint poetic echoes the machine retained from the dissolved data.
Output
forgetting_engine.py— self-contained Python scriptartifact.json— structured dream artifact with entropy stats and memory traces
Run
python3 forgetting_engine.py # static report
python3 forgetting_engine.py --animate # animated terminal visualization
Algorithm
- Entropy harvest: SHA-512 of PID + uid + time_ns + datetime.now() + urandom
- 2D field: bytes → floats via staggered 32-bit little-endian windows, modulated by sine-wave interference
- Diffusion: 2-pass neighborhood averaging (memory bleeds outward)
- ASCII map: 8-level density ramp (
·:;+*#%@) - Memory traces: floats > 0.55 mapped to a curated word list — poetic fragments
- Artifact: SHA-256 artifact ID, Shannon entropy, trace count
Artifact Example
- Artifact ID:
1bb4d065bc9e - Shannon H: ~4.04 bits/symbol
- Memory traces: lattice, the other side, fragments, vessel, shadow, boundary
Terminal capture of the overnight run is embedded above.
