Flowsnake visualization of structural protein sequence for covid19
View README.md

Illustration of how to convert from traditional axial (or cubical) hex coordinates to and from two one-dimensional enumerations based on space-filling fractal curves. The spiral honeycomb mosaic enumeration recursively labels nested "super hexes" in base 7, starting from 0 at the origin. The flowsnake enumeration also call "Gosper7" here, recursively labels the same super hexes but in a continuous sequence with no jumps.
This uses a negative base 7 with an unbalanced signed representation using the digits = (-2), - (-1), 0, 1, 2, 3, and 4. These enumerations could be useful for compact visualization of one-dimensional sequence data as well indexing hexagonal data storage with good locality properties similar to the Hilbert curve.

This example shows a simple visualization of the structural protein sequence for covid-19,

Hex cube visualization

Sadly the original bl.ocks.org seems to be dead. Hopefully you can still see the visualization at this clone.

Inspired by Amit Patel's diagram illustrating cube coordinates. That diagram initially confused me because the edges of the grid cubes centered on integer coordinates in the plane x + y + z = 0 don't themselves lie in the plane, so it seemed like the animation "cheated" at the end by dissolving to planar hexagons. But of course the point is just that the silhouettes of those cubes form a perfect hexagonal tiling of the plane. That tiling is highlighted as red hexagons here.

I made this animation to get a better intuition for how those cubes intersect the zero plane. It shows what happens as we slice the cubes at x + y + z = w while reducing w towards 0. Fittingly the slice where the zero plane intersects each cube is in fac

Simple D3 clock
View README.md

A simple clock made with D3.

After I'd made it I got a bit caught up in trying to make it look like Dieter Ram's Braun clock face adding a whole bunch fo extra stuff...

It's still not quite there.
