The golden angle behind sunflowers and pinecones — grow a floret pattern one seed at a
time and watch the spiral arms emerge, with full control over the generation angle,
field size, and growth speed.

Predator-Prey
The Lotka-Volterra equations behind every predator-prey cycle — watch two populations
rise and fall in a feedback loop of growth and predation, with live population and
phase-plane charts, and full control over every rate.

Stroboscopic Effect
Why a spinning wheel can appear to freeze, creep forward, or spin backward under a
strobe light or camera — watch the true continuous motion next to what the strobe
actually samples, with full control over spoke count, rotation speed, and strobe rate.

Double Pendulum
Two nearly-identical double pendulums, one a fraction of a degree apart at the start, torn
apart by chaos — watch how a system with no randomness anywhere in its equations can still
become impossible to predict, with full control over mass, length, gravity, and starting angles.

Light Polarization
How stacking angled polarizing filters can block light — or bring it back. Rotate
each filter, add up to eight layers, and watch the transmitted light respond exactly to the
angle between each filter and the one right before it, following Malus's law.
