Welcome to the Symmetric Pen! It's a tool that allows you to draw perfectly symmetrical pictures by just clicking and dragging! Or, if you don't want it to be symmetrical, just press the N key, and you'll be back to just one pen at a time. Change your mind? Press the S key to go back to symmetry! If you want to change your pen color or size, press the C key to bring up the control panel, and then use the sliders to change the different attributes of your pen. Once you're done, press the C key to hide the sliders again. If you want to start over, press the spacebar to erase your entire drawing.
