Processing

For my processing assignment I created a line that not only gets larger as the mouse moves faster or slower, but the color also will change when either the right or left mouse button is clicked.

For the critique it was suggested that I create a background and use a function key to "erase" the image that was being drawn. So I went in and did that but now, once it erases you have to press another keyboard key for it to get to draw again. So I'm trying on fixing that right now. But here is a screenshot of what it looks like when there is drawing.
