The goal of my project was to create a virtual paintbrush and canvas using Processing. I wanted the user to be able to choose colors via keys and manipulate their mouse or touchpad to paint anything they wish.(also works well with Wacum pen/pad) I used an array to hold the brush colors and corresponding number keys to choose each value. The brush size is determined by the variable 'd' which controls the diameter of the ellipse which functions as the brush shape. If you want to start over hit BACKSPACE or DELETE. When you have finished your masterpiece hit 'S' to save a screenshot.
