This is a Java sketch that includes (all of these):
- One element controlled by the mouse.
- One element that changes over time, independently of the mouse.
- One element that is different every time you run the sketch.
I made an illustration at the beginning for a better image of what I will be making.
I use the alpha background to create this glowing effect, and [if] statement for keeping each ellipses moving in a specific pattern. Interact with your mouse.
