## The Artist's Husband: Warping the Grid

The Entanglement library has a few grid-based tangles now: Huggins, W-2 , Ambler and Emingle. But we have limited control over the grid: we can affect the spacing in the x and y directions, and we can add some random fluctuations to where each intersection on the grid ends up. Wouldn’t it be nice if we could warp the grid in some more dramatic ways? Yes, I thought so too!

## The Artist's Husband: Huggins and W-2

Huggins and W-2 have appeared in the Entanglement library! Huggins and W-2 both look like they have been woven but are really just shapes on a grid connected by lines according to a few simple rules. The difference between them is that Huggins connects circles with curved lines, while W-2 connects squares with straight lines. In this post, I’ll talk about how I built Huggins (once you build Huggins, W-2 is pretty easy to add) and show some examples of how both are used.

## The Artist's Husband: Creating a New Tangle

The Entanglement library has a very few (so far) tangle patterns built in which can be used to create Zentangles. New ones get added to the library as I get to them, but you (yes, YOU) as a user can create them too. Warning! This post is mostly Javascript code! If that’s not your thing, avert your eyes now! You need version 0.0.5 of Entanglement to follow along:

## The Artist's Husband: Let's Make A Zentangle!

Up until now, the Entanglement library has provided a few tangle elements and a few tangles, which you could draw onto your canvas. But real Zentangles have a border, and might be round or triangular instead of square. To make this easier to do, Entanglement now has the Zentangle class. This is the top-level class you should use to define what your Zentangle should look like. Here is an example using it.

## The Artist's Husband: Box Spirals

Recently I did a post about the Ambler tangle in the Entanglement library. Ambler uses an element called a box spiral. It turns out, box spirals appear in several tangles, most notably the Box Spirals tangle. In this post, we’ll talk about the Entanglement BoxSpiral class, which implements the Box Spirals tangle. The box spiral used in Ambler as it is implemented in Entanglement is very specific. It consists of nine lines, and always rotates counter-clockwise.

## The Artist's Husband: Ambler

The Entanglement library now supports Ambler! This officially doubles the number of tangles it can produce! Two tangles! Progress! OK, so two tangles isn’t really all that many, but still! Progress! Using Entanglement to draw a basic Ambler is easy. Here’s the program that generated the image at the top of this page: const height = 600; const width = 600; function setup() { createCanvas(width, height); background(255); } function draw() { let amb = new Ambler(width, height, {}); amb.

## The Artist's Husband: Entanglement

In my last two posts, I showed how to draw most of the Aah tangle using the Javascript p5.js library. In this post, the Aah is complete, as you can see from the image below. However, the Javascript code to do so, does not follow directly from what we saw in those previous posts. I have rewritten it and packaged it into a library: Entanglement. More about that shortly.
