SUN-EARTH-MOON SYSTEM VISUALIZER
The Moon in this rolling-coin model shows real phases, and its tidal lock can be switched off. An observer's sky shows when the Sun and Moon are both above the horizon. Periods and phase geometry are faithful; distances are not to scale.
SOLAR SYSTEM
This renderer draws the solar system from NASA JPL Horizons data for any date from 2001 to 2031. It can run a timelapse or show only the moons. Any frame saves as a wallpaper.
SATURN V ASCII LAUNCH
A truecolor ASCII engine plays the Apollo 11 liftoff each time I open my terminal. It simulates the flames, and the smoke dissipates from the top down. It streams the full NASA footage in 2MB chunks of colored characters. Install instructions are in the repo.
PERSISTENT MEMORY FOR LLM AGENTS
aelfrice keeps LLM agent memory between sessions as Bayesian-scored beliefs. Retrieval runs on FTS5 keyword search and typed knowledge graphs. There are no embeddings. It detects corrections without LLM calls (92% accuracy) and bridges vocabulary gaps at 99.5% recovery. Version 4.0 added junk demotion and temporal-spine retrieval, which raised coverage 14.6pp on a fresh LoCoMo sample. I publish benchmark re-runs, including ones that scored lower.
DIFFERENTIABLE ROCKET SCIENCE
This neural net learns spacecraft maneuvers by backpropagating fuel cost through the physics. On the full 3-D task it circularizes 92.3% of random orbits, and its best-fuel checkpoint uses 1.03x the analytic-optimal fuel. From the raw objective it rediscovers an operational J2 maneuver and flies a verified ballistic lunar capture with no capture burn. In 2021 I tried to train an RL agent to fly to the Moon for a grad astrodynamics course, and it never learned anything. In 2026 I found the real bugs and rebuilt it. The 2021 code is in the repo unmodified.
MINING SATURN'S RINGS
The concept hauls multi-tonne blocks of 99.7%-pure water ice from Saturn's B ring to Earth orbit. The ice cargo is also the return propellant tank. I falsified it in 215 pre-registered analysis rounds. Under closed-loop mass accounting, none of 1,744 mission paths completes the round trip. The one paper corridor left needs three unproven technologies, and the financial model puts breakeven at 3.1 times the top defensible water price. The retractions are in the repo next to the claims.
