Laser Pointer Googly Eyes

Laser Pointer Googly Eyes

I am glad I can amuse myself. This is a simple script that I may integrate into an Algebra class for looking at points on a line. If you want a webpage version for students, click here. If you want code, see below. Click to make more eyes, and you might get freaked out if […]

Fractal Ink to Code

Fractal Ink to Code

After drawing the fractal prompt today for Mathober, I played around to make it in p5js. Below is the Codepen to play with. I almost feel like it should have a surprise when they align…maybe for another day. See the Pen fractal_Mathober by Sophia (@fractalkitty) on CodePen.

Lune of Hippocrates Clock

Lune of Hippocrates Clock

After drawing the Lune of Hippocrates yesterday for Mathober, I played around to make a Lune clock today. Below is codepen (p5 is here). I use a lot of these small projects for students to play with in an hour of code group. This one may not be as popular as projecting memes and cats […]

Fantasy Maps to Planets

Fantasy Maps to Planets

For those that have created fantasy maps using previous posts here, in classes, or elsewhere in Worldbuilding, D&D, or art, I created a small script to see your maps as spherical planets. You can click to rotate and move the mouse off the canvas to have rotation. You may want to draw a map that […]

Random Math Poetry

Random Math Poetry

I think the challenge here is to find the math that can fit the poetry… If you want a browser tab version, click here. You can also edit it and change the words as well. Below is the codepen: See the Pen OJNKQmE by Sophia (@fractalkitty) on CodePen.

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!

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.

Parallel to a Parabola

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.

SA8: Odd and Even

SA8: Odd and Even

This Scripting Algebra (SA) activity uses even and odd polynomials to create generative art in p5.js. This activity assumes that the skills from SA1-SA7 were introduced (if-else, logical operators, random(), text(), rect(), variables, loop, pow, for, functions, translate etc.). This activity will in

SA7: Directrix and Focus

SA7: Directrix and Focus

This Scripting Algebra (SA) activity uses parabolas again to make generative art in p5.js. In SA6, we used the f(x) = ax2+bx+c form for parabolas. In SA7, we are going to take a look at the directrix and focus by using the form: (x-h)2 = 4p(y-k). This is one of my favorite ways to look […]
