For this project I partnered up with Yuening Bai. We knew that we wanted to have something following the mouse, and we discussed pulling images from the web and having the ball actually be a cat, so that it is chasing the mouse. I ran into some trouble trying to code this, and could only figure out how to load a photo from the hard drive of the computer, not from the web. So instead we made it a ball that got smaller as it got closer to the mouse. I originally figured I would do this by making the height and width of the circle correlate to the distance from the mouse in the x and y directions. This had an effect similar to what i was going for, but the circle would disappear if you backtracked from the bottom right of the screen to the top left. To solve this, I made it instead the absolute value of dy and dx.
