Interactive pages that let you turn the handle on parts of the program yourself.
Interactive kernel dynamics: a finite rule with unbounded evolution, stepped in exact integer arithmetic.
Penrose tilings as a Galois projection of ζ ↦ ζ².
The Mandelbrot set as escape-time counting, z ↦ z² + c. Time as a counter, in the small.
Axiom: J = 1 + j². Time is a counter. Space is a commutator. Exact arithmetic first. Plenum, not vacuum.
