Probability
Galton Board
Drop a thousand beads through a field of pegs and watch pure chance pile into a bell curve.
The collection
A cabinet of curiosities.
Each piece is one idea, built until it clicks — then left out for anyone curious enough to play. Drag things, scrub the sliders, push them past where they ought to go. That’s the point.

General relativity
Over the Event Horizon
Space pours into a black hole like a river, and the event horizon is where the current outruns light. Fire flashes at the edge to see what gets away — then drop a ticking beacon and watch it freeze. From the outside only.

Everything in the cabinet
10 curiosities
Fractals
The Fractal Copier
A photocopier that prints shrunken copies of whatever you feed it — then copies the copy. Feed it a square, a letter, your own doodle: the same shape emerges every time.
Phyllotaxis
Fibonacci in Bloom
Seeds placed one golden-angle turn at a time count out 34 and 55 spiral arms — drift a tenth of a degree and it all shatters into spokes.
Acoustics
Whispering Gallery
Why two people far apart can hear each other’s whispers — when the walls have exactly the right curve.
Analysis
Fourier Drawing Machine
Stack enough spinning circles and they’ll trace any shape you like — one epicycle at a time.
Geometry
Ellipse Explorer
One curve, many machines — and what breaks when you add a third focus.
Dynamics
Three-Body Problem
Three masses, one rule of gravity, and orbits that refuse to repeat. Nudge a start by a millionth and watch the future fly off somewhere else.
Number theory
Prime Spiral
Coil the integers into a square spiral and the primes fall onto strange, stubborn diagonals.
Networks
The Phantom Shortcut
Hundreds of selfish drivers pour onto one free shortcut and make every trip slower. Cut it, charge a toll, or rewire the city — Braess's paradox as a living network.
