You can find a fullscreen demo at /projects/gooey/, or a smaller version if you skip to the end of this post. For the full code, see the JS code and vertex and fragment shaders.

The options panel in the top left of this page lets you change the variables in the animations.

AllRGB is a really cool challenge: make an image that contains each of the 16777216 RGB colors exactly once.

I wrote a HTML canvas-based visualization of an AllRGB image being created. It uses several space-filling curves in 2D and 3D.

I made a demo of this at /projects/allrgb and the source is on GitHub.

Color models

If someone knows only one color model, it's probably RGB. It's a great color space for computers to represent colors, but not intuitive or useful for humans. It's especially not useful when objectively determining whether a color is dark or light.

Introduction

Chances are, you've once wanted to make a progam for generating or solving mazes. There are dozens of maze algorithms. In my opinion, Kruskal's algorithm is the simplest for generating mazes.
I made a demo of this at /projects/kruskal.
