//This is Exercise 1 through 3 at the end of Structure 1 in Processing

/*I think it would be great to write some software that allows a user to
 manipulate shapes with their body. In other words, a visual theramin. Processing would read video input and have
 some sort of function that would enable it to respond to the fluctuation in light 
 as someone moves before the camera, and that would translate a shape. Depending
 on how quickly the person moves, or how close they are to the camera, the shape
 will change accordingly. The following code has nothing to do with this idea.*/

  size(640, 480);
