That's a Moiré
The title of this post comes from this comic [https://xkcd.com/1814/], although it's a topic I've been planning to write a bit about. Moiré patterns [https://en.wikipedia.org/wiki/Moir%C3%A9_pattern] are wavy effects that appear when two regular patterns (grids, parallel lines, etc.) with
Stochastic tiling script
A bit over a year ago, I wrote a post about the mathematics of tiling [https://danbscott.ghost.io/a-tiling-primer/]. In this post, I explore some of those ideas further with an octave script I wrote to draw regular and semi-regular [http://www.wolframalpha.com/input/?i=semi-regular+tiling] tilings.
A tiling primer
This post is a brief introduction to the mathematics of tiling, which I find quite fascinating. Tiles [https://en.wikipedia.org/wiki/Tile] are a long-standing architectural feature. They have been used in cultures all over the world, but the math underlying how they can cover a space [https://en.
3D-Printed Cactus Pot
This post is about one of my recent 3D-printing projects. Cactus I like having plants in my apartment, but anything that requires frequent attention would have a difficult time surviving under my care. I thought cactus would be a nice fit, due to their ability to withstand periods of water
One of my favourite topics in math is fractals. For this post, I drew the Hilbert Curve fractal in octave. The Hilbert Curve [http://en.wikipedia.org/wiki/Hilbert_curve] is a space-filling curve: although it is one-dimensional (a series of line segments) itself, it covers a two-dimensional area. I
Writing an .stl file from scratch
The .stl file format [http://www.ennex.com/~fabbers/StL.asp] (see also [http://en.wikipedia.org/wiki/STL_%28file_format%29]) is used for 3D printing and similar fabrication technologies. The files are normally created as output from design software, but I wanted to try writing one by hand
