When I was younger, I had a knack for drawing on napkins wherever I went. This Processing project attempts to mimic this activity of drawing on a napkin. The concept is very simple. Clicking starts drawing lightly. You will notice how the lines are blocky and jagged, similar to the lines created from drawing on a napkin's rough surface. Right-clicking switches back and forth between pressing hard and pressing lightly. Note: to get the pressure switching to work properly, hold the right-click button for a while or click it twice, then proceed drawing. To start drawing on a new napkin, or reset, click the blue button on the top left. Towards the top right, you can change the color of your pen by clicking on the appropriately colored red, blue and black squares. You can access the applet here as well as the source code here. Note: for some reason, the applet only chooses to work sparingly. The best solution is to run the jar file or the Project4.pde code within Processing.
