NEURAL OBSERVATORY · BUILT IN PUBLIC
One builder's living laboratory — neuroscience, energy, and play.
This isn't a startup pitch. It's one person building a brain app, a solar research bench, a marble arcade, and a 3D town — all in one codebase, all in public.
Some of it works. Some of it is a prototype. None of it is finished. That's the point.

ESTIMATED PAYBACK
11.4 yrs
≈ $1,314 saved / year
No-fibs: rough arithmetic — assumes an 80% system derate and $0.15/kWh, ignores incentives, degradation, and your actual roof.
One of ten brain labs runs this exact drill and saves your history — here it's a throwaway.
Tap a swatch to decode the tactic behind it.
No-fibs: illustrative patterns from common marketing playbooks — not exhaustive, not a science.
No-fibs: a self-recorded span — not a clinical working-memory assessment.
tap the ink color, not the word
No-fibs: the classic Stroop interference effect — a self-recorded demo, not an attention diagnosis.
No-fibs: a curated, illustrative set — real etymology is messier than four neat buckets.
ESTIMATE
~5 tuners
households ≈ 227,273
pianos (1 in 50 homes) ≈ 4,545
each tuner does ~1,000 jobs/yr
No-fibs: a Fermi order-of-magnitude estimate — the point is the reasoning chain, not a real census.
2 × 2 × 3 × 5
3 distinct primes
No-fibs: exact integer factorization — the math is real; this is a toy, not a research tool.
No-fibs: click two stars to connect them — pure play, not real astronomy.
ready
No-fibs: a toy 2-body integrator — not real astrodynamics; orbits can drift from the simple math.
tap 4+ times to measure your consistency
No-fibs: a self-recorded timing toy — not a clinical motor-coordination test.
TARGET
YOUR GUESS
0/100
121° off
No-fibs: a color-matching toy — not a vision or color-perception test.
10 neuroscience labs
Self-recorded cognition — reaction time, memory, prediction. Not medical measurement.
Solar & materials research
Grounded in real, cited sources. Not a manufacturer, not a lab, not a guarantee.
A 3D walkable town
Community storefronts you can stroll. Not a marketplace, not transactions.
Marble games & forge
Procedural textures and arcade games. Not real glass, not physics simulation.
Linguistics & code bridge
LLM translation of English to code. Not executed, not compiled, not tested here.
An honest changelog
A no-fibs build log of what actually shipped. Not marketing.
