# Project – Dynamic Drawing

My process was starting with a sketch and then systematically testing and working out the individual controls for each circle.

createCanvas(600, 450);

var grayscale = max(min(mouseX,255),0); //as mouse moves right circles become lighter
var size1 = max(min(mouseY,227),70); //increases size as mouse moves down. Min diameter is 70, max diameter is 227
var size2 = 297 - size1; //opposite of size 1, makes the middle circle have the opposite diameter of the other two
var yShift = constrain(mouseY,0,height/3); //as mouse moves down circles move down
var yShift1 = -yShift; //two circles move opposite direction of center circle
//mouse makes different messages appear
if(yShift == height/3){  //when the middle circle is at its lowest position the message "Et hoco modo nihil" appears
textSize(45);
fill(abs(255-grayscale));
