This is a sample p5.js sketch for HON 291! Move the mouse around in the space above.

Here's the code:

function setup() {
     createCanvas(500,500);
     background(240);
}
function draw() {
     fill(abs(255-mouseX-mouseY),(mouseX*mouseY)%255,mouseY);
     circle(mouseX,mouseY,abs(mouseY/10-mouseX/10)+10);
}
