From sorting algorithms you can watch race each other to geodesic
domes you can build in three clicks — the Math & Algorithms
category is one of the richest on the site. Here's what's in it and
where to start.

Mathematics is the language of every simulation on this site, but the
Math & Algorithms category puts the maths itself front-and-centre.
The focus is on visual intuition — seeing why Euclid's algorithm
converges, watching A* navigate a maze, or rotating a geodesic dome to
understand its structure.
If you're new to the category, start with
Sorting Algorithms — it's the
most instantly understandable and often the best hook for students
who've heard of bubble sort but never seen it lose.
If you're comfortable with discrete maths, go to
Travelling Salesman next. Watching 2-opt improve
a greedy tour over hundreds of iterations is a better explanation of
local search than any textbook diagram.
For geometry and visual maths,
Geodesic Domes and
Spherical Projections are the
most visually striking. The spherical projections demo was built
specifically for geography and cartography courses.
Behind the Algorithms
Most of the Math category uses plain Canvas 2D — the algorithms are
the work; the renderer just needs to get out of the way quickly. The
two Three.js exceptions are Geodesic Domes (genuine 3D geometry) and a
forthcoming 4D hypercube demo.
Up next in Spotlight #2: the Quantum Physics &
Quantum Computing categories — Bloch spheres, Bell states, and
Grover's algorithm in your browser.
