8 projects Things I built to connect my life or answer questionsPlease Remain Seated
Why getting off a plane takes forever: race exit orders, then rank every airline's real 2026 boarding procedure.
Grid Atlas
Where does your electricity come from? Type your ZIP and meet your grid — fuel mix, CO₂ per kWh, prices, and 25 years of change, drawn from public EPA and EIA data.
EV Atlas
How fast is the world going electric? EV adoption across every US state and country, the battery-price crash that made it possible, and 200 years of electric-car history — built on IEA, US DOE, and BloombergNEF data. A sibling to Grid Atlas.
After the Decimal
Why does every AI lab ship a .5, and why does nobody ship a .9? A visual survey of 109 flagship LLM releases from 14 labs, 2018–2026, tracing what the digit after the dot really signals.
Monarch Money CLI
A full-featured CLI for Monarch Money. Query accounts, transactions, budgets, and cashflow from the terminal — JSON output for AI agents, clean tables for humans.
Real-time travel in the bay
The Bay Area redrawn so distance means travel time. Drag a slider and watch two-mile bridge crossings stretch wide while freeway miles shrink, all routed over the real OpenStreetMap street network.
Birds-Fly View
Type any Bay Area address and take off as a bird — real streets, real building heights, real terrain, rendered as a golden-hour dreamworld from live OpenStreetMap data.
Coop View
The family backyard rendered live in 3D: real satellite ground, our two hens Pidgey and HeiHei wandering the lawn, and a sky that tracks the actual sun, moon, and stars. Password-gated to keep the location private, so bring the passphrase.
Learning
9 projects Interactive sites that teach ideas intuitivelyHole Foods
You are a hole, and everything is food. Swallow berries, cakes, cars, then whole city blocks — the further you roam through an endless emoji world, the bigger everything gets, forever.
From Attention to Agents
The story of modern AI as one arc — from the 2017 Transformer to today's reasoning agents. Eight chapters of interactive demos: self-attention, scaling laws, RLHF, test-time compute, and the agent loop.
Valence
Chemistry from first principles. Rotate real electron orbitals in 3D, watch energy levels cross to explain the periodic table's shape, and build molecules with live octet checking.
Solidified Sky
A tree is made of air. Fly down into a living chloroplast and travel through photosynthesis while it runs - water splitting into the oxygen you breathe, a single carbon riding from air into sugar. Every molecule drawn and animated in code.
Graph Playground
Animation-first intuition for function transformations: why subtracting 3 from x slides a graph right, why a minus sign flips it. Color-coded knobs, a copycat race, and boss levels.
Follow the Drop
Be a drop of water. A choose-your-own-path adventure through the water cycle for young explorers — evaporate from the ocean, ride a cloud, fall as rain, keep a travel journal.
Diffusion From Scratch
An 11-module curriculum building the full pipeline behind Stable Diffusion and DALL·E 3 in PyTorch — from noise schedules and U-Nets through latent diffusion, DiT, and flow matching.
CS224R: Deep Reinforcement Learning
Open-source study companion for Stanford's CS224R. Eighteen detailed lecture notes spanning imitation learning, policy gradients, offline RL, RLHF, and sim-to-real robotics — the deep-learning sequel to CS234.
CS234: Reinforcement Learning
Open-source study companion for Stanford's CS234. Fourteen detailed lecture notes covering MDPs, Q-learning, policy gradients, imitation learning, and exploration — with rendered math.
