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:
Made a binary adder as well
no idea why i do these things
For some reason I have built Conway's Game of Life in Baba is You.
My latest bloggy thing:
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 π-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 —
[1, 2] → 12
⟨1, 2⟩ → 21
⟨[⟨1, 2⟩, 3], 4⟩ → ⟨[21, 3], 4⟩ → ⟨213, 4⟩→ 4213
…we can make any number except 2413, and which other?
I wrote a thing for the Aperiodical:
This is a nice little trick but a bafflingly poor article. How can anyone write an entire article about a single tweet without having understood the tweet?
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!
Here’s 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 embroidered computer is lovely. I think it works by the gold coils over the large beads being magnetically drawn to one side or the other of the base — and therefore making different connections — depending on whether or not a current is flowing through them.
This is lovely, an interactive demo of Fourier transforms
