I built upon my sketch from last week for this assignment on arrays. I was nearly done when I thought I'd add a println command to see what happened. It crashed Processing on my computer, erasing my work. This is my second attempt at this . The ellipses are not so much comets anymore. Try pressing the mouse and also try putting the mouse in the upper right corner.
