From the Void
Hexagon and parametric spiral play. I find myself doodling with code lately more than with my pen. I have one more scripting algebra post, but feel like I have a much larger library for a pre-calc set of activities. Thoughts? The GIF is too large for this site or twitter, so I stashed it on […]

SA9: Quadrant Play
This Scripting Algebra (SA) activity looks at quadrants, mouse location, and interactive art p5.js. This activity assumes that the skills from SA1-SA8 were introduced (if-else, logical operators, random(), text(), rect(), variables, loop, pow, for, functions, translate, modulo, etc.). This activity

Parametric Play!
Here are some simple animations with parametric equations. What you see below is a function and its inverse. If you click, you will get another semi-random equation. See the Pen qBZgZvW by Sophia (@fractalkitty) on CodePen.

My daughter started playing with moiré in procreate after I fiddled with it in a previous post. You know we breathe math in our home. She wanted to share:

Parallel to a Parabola
I received a question today about what curve is parallel to a parabola. I sat for a minute and realized that it wasn’t another parabola. It required parametric equations (at least if you wanted to keep it simple). That of course lead to code: See the Pen jOqzMJb by Sophia (@fractalkitty) on CodePen.

Hex-a-Sierpinski
So I doodled and was pleasantly surprised when Sierpinski-like triangles formed. I am sure that a million people have discovered this before me, but I felt like I found a magic portal. And that lead to coding (of which is currently a mess, and I will post later). And one more version:
