Math Night

Fun demonstrations for getting kids interested in math (and graphics).

Times Table Circles

Place N points around a circle, connect k to k×M modulo N. Animate M and watch cardioids, nephroids, and interference patterns emerge.

Voronoi Diagrams

Plant seeds and watch territories form. Each region belongs to its nearest seed. Seeds on the boundary get contrasting colors; interior seeds blend from their neighbors.

Prime Sieve

Animate the Sieve of Eratosthenes on the 100 chart. A volunteer narrates as each prime lights up and its multiples get crossed out one by one.

Rigid Body Physics

Configure shapes, bounciness, and gravity — then DROP. Watch the physics engine simulate collisions, friction, and tumbling in real time.
