Inspired by Everest Pipkin’s Moth Generator, I use trigonometry and perlin noise to procedurally generate butterfly wing designs with p5.js.

In this coding challenge, I look at extracting font path points from text in p5.js with p5.Font.textToPoints(). I render the text as particles with steering behaviors that react to the mouse.

In this coding challenge, I follow up on the Earthquake Data Visualization challenge and create a 3D version in Processing(Java) using spherical coordinates. I also discuss some 3D vector math including the cross product.

In this coding challenge, I visualize earthquake data from the USGS by mapping the latitude, longitude and the magnitude of earthquakes with p5.js. The map imagery is pulled from mapbox and the math demonstrated converts latitude, longitude to x,y via Web Mercator.

In this challenge, I create a particle system and add "attractors" simulating attraction and repulsion forces.

In this coding challenge, I attempt to create rose (rhodonea) curves using trigonometry function and polar coordinates.

In this bonus super-sized coding challenge, I work through visualizing Islamic Star Patterns in p5.js.

In this coding challenge, I simulate a "random walk" with vectors in p5.js, varying the distance of each step size. This is known as a "Lévy Flight" (named after french mathematician Paul Lévy.)

In this coding challenge, I simulate a "random walk" with the p5.js library. This video is part of the course Nature of Code at ITP, Tisch, NYU.

In this multi-part coding challenge, I attempt an implementation of the A* Pathfinding Algorithm to find the optimal path between two points in a 2D grid.

In this multi-part coding challenge, I demonstrate how to use a circle packing algorithm.
