This predates my Mastodon accounts but it ought to be on here so here it is: my interactive blog about the domino computer.

@andrewt As if this weren't all confusing enough, I believe the set of points depicted here is what's technically known as collielinear.

@andrewt It's the prefix col- which sometimes occurs in latin-derived words instead of co- or com- with base words that begin with an 'l'. You see it in "collateral" and "colloquial" and even in "college" and "collegial." That said, I think the one-l version, "colinear" is widely accepted as correct these days.

update: it works with 3d rotation too: https://www.shadertoy.com/view/tljSRG

Someone posted a gif of this effect on birdsite and I wanted to understand it so I've built it as a space-warping raymarcher.

Its some lovely maths that I think I *mostly* understand now:

For some reason I have built Conway's Game of Life in Baba is You.

As always, comments, thoughts, criticisms, and feedback, all welcome.

Have to say that this "one blog post per week" is a brutal schedule.

Also, here's a maths puzzle for Ο-day:

Adding the brackets from this Alex Bellos column https://www.theguardian.com/science/2019/mar/11/solve-it-can-you-speak-yoda-how-to to the numbers 1, 2, 3, 4 β

[1, 2] β 12

β¨1, 2β© β 21

β¨[β¨1, 2β©, 3], 4β© β β¨[21, 3], 4β© β β¨213, 4β©β 4213

β¦we can make any number except 2413, and which other?

I wrote a thing for the Aperiodical:

This would make a strong contender in the MathsJam bake off.

Also v good doggo in VR, which is a plus

Try it for yourself at http://www.michaelwoodard.net/hypVR-Ray/, it even works on phones!

Hereβs a video on simulating a non-euclidean space in virtual reality with ray marching. This project is joint work with Michael Woodard and Roice Nelson. https://youtu.be/ivHG4AOkhYA

This is lovely, an interactive demo of Fourier transforms
