Featured Challenge:
#184 — Elastic Collisions

What happens when two circles collide in a p5.js canvas? In this video, I examine the math and implement idealized elastic collisions in a physics simulation. This video supplements the Nature of Code book series in Chapter 6 which uses 3rd party physics libraries to handle collisions rather than a direct implementation.

In this holiday coding challenge, I create a "Brownian Tree Snowflake" in Processing (Java). This video was recorded as part of a fundraiser for the Processing Foundation.

In this coding challenge, I explore the generative algorithm "Diffusion-Limited Aggregation". The pattern is generated from random walkers clustering around a seed (or set of seed) point(s).
