A simple interactive animation of (shallow) water waves propagating on variable depth

This is a simple code for generating autostereograms -- a way of hiding 3D objects in 2D patterns. There is also a text explaining how it works... sadly, the dynamic autostereogram is too slow in its present state, and I don't feel like spending time making it work.

3D visualization of the vibrational eigenmodes of a circular drum membrane

A very simple raytracing simulation of a black hole attached to the mouse, lensing a star in the Andromeda galaxy.

A visualization of how pretty fractals can emerge from probabilistic processes.

This is a simulation for visualizing the dynamics of the Lorenz system and its bifurcation.

This is a simple visualization of Complex mappings. That is, it parametrizes and animates the effect of complex mappings on a cartesian grid on C.

This is a simple code for visualization of the diffusion-limited aggregation algorithm for computing particle aggregation in systems such as the Hele-Shaw cell.

A simple visualization of a double pendulum.

Visualization of the physics of elastic collisions

This is an extensive, but basic experiment with reinforcement learning. Digital 'Animals' spawn with random DNA and blank brains. With mutating the neural network for every new boid, they gradually evolve to handle the environment better. There are three views: The simulator itself, a visualization of the 'best' boid and a control panel where environment and mutation properties can be altered. Have fun!

Visualization of how chaos emerges from applying simple functions repeatedly.

This is a simple code for visualization of the discrete Fourier transform using epicycles. You can draw an arbitrary graph and play with the number of circles (which amounts to a Fourier filtering) and the parametrization speed.

This is a simulation of the 'game of life'. More information on the page :)

Find countries on the world map as fast as you can.

Some famous fractals and sliders and knobs for controlling them.

A real-time visualization of the Ising model for a two-dimensional grid of half-integer spin particles. You can control inverse temperature to discover the ferromagnetic phase transition.

Just a silly simulation of particles interacting via the Lennard Jones potential.

A Verlet physics simulator for mechanical linkages.

This is a simple rendering of the Mandelbrot set together with a visualization of certain trajectories. More info inside.

A small ray-tracer for calculating the trajectories of refracted and reflected rays of light of generic surfaces.

A naive, but beautiful approach to automated art based on the way ants track paths.

Simulation of planets (or circles if you want) that interact gravitationally and merge conserving mass (area), momentum and center of mass.

A devoted rendering of how rays refract and reflect through a drop of water.

Interactive visualization of water wave dispersion including gravity and surface tension effects

Interactive map showing where shadows of a 1m stick land throughout the year.

This is a simple visualization of how the seed pattern on a Sunflower arises from producing seeds separated by the golden angle. You can try other ratios to convince yourself that the golden angle is an optimal choice. Also, choosing other irrationals can shed light on approximating fractions, like 22/7 for pi.

Real-time simulation of the wave equation with custom barriers and damping.

Just a small code for generating (semi-)realistic two-dimensional trees.

Well... some voronoi stuff

This is a small script for visualizing two-dimensional, classical vortex dynamics in incompressible fluids.

The shape of droplets

A simple tool for playing with 3d dynamical systems

A realtime (...ish...) view of our solar system.

This is a simple code that allows for a visual exploration of the 17 fundamental symmetries of a two-dimensional surface -- the so-called wallpaper groups. After you pick one of the 17 wallpaper groups, a gray rhombus will display the fundamental translated area. On top of this, there are lines showing mirror symmetries, glide reflections and discrete rotations. Enjoy!
