This is an applet to draw tilings on your screen. Push the buttons to change the tiling. The two numbers under "Dual" restricts the n-gons that "Tri", "Quad", "Penta", and "Inset" will affect. It will only affect n-gons with n between the two numbers given - inclusive. The zoom factor at the top of the screen... uh... zooms. :) For more detailed instructions on using the applet click here.
