This is an update to a post from March 2, 2012.

From 2002 to around 2012 I devoted most of my creative energy to programming. I created well over a hundred visual toys and simple games, and kept the momentum going until a series of life events sucked the mental and emotional energy from me. When I got my life back I turned my creative energies to writing fiction and poetry, and my decade-plus of experiments in mathematics, geometry, cellular automata and game design fell by the wayside.  Most of those experiments were in Flash and though I still have the source code rebuilding them in Javascript would be an extremely time-consuming project.

But some of those experiments were in Javascript, particularly after I saw the writing on the wall for Flash and Actiosncript. This is one of those experiments – a 3D version of the Langton’s Ant cellular automation, created using hand-rolled Javascript, with an assist from the Three.js 3D rendering library.

Here are a couple more screenshots from later iterations of the algorithm:
