Final 2: Fireworks worm

This is my final for processing. I experimented with the mousex and mousey functions to make the ellipse follow my mouse around. I have included the easing function so there is some delay after the mouse moves. I have included multiple ellipses to follow my mouse all with an increased amount of ease to create a trail behind the first ellipse. I have experimented with randomising colours and opacities. Unfortunately I had aimed to include the mousePressed function to create a new ellipse to join the trail every time I pressed the mouse. I spent many hours trying to achieve this but was never successful. I was also unsuccessful in creating a for loop for the ellipses so i had to type the code out manually. I like this composition because it is satisfying to watch the ellipse morph into one another when the mouse is kept still after movement.
