This is my first attempt with pens, and Broadcasts, and also my first real project. I hope you like it!
Click a color to change the brush to it. Click on the arrow to change the background, and the red to orange button to change the ackground shade. The "X" deletes the drawings, the "+" increases the pen size, and the "-" decreases it.
V.1: Black now works; cursor is now more visible; and the pen now moves non-linnear-ly (its not all zigzaggy anymore!)
