Use arrows keys to move the pen like an "Etch A Sketch" Space to clear the board like shaking an "Etch A Sketch" If you put a 1 in for the number of sides it will just make a straight line to the right. Put in a zero to abort the process. The pen can be picked up and dragged to move it without drawing. Possible colors: "( )" means alternate spelling; do not include "( )" white light red (pink) red dark red orange yellow lime light green green dark green light blue blue dark blue indigo purple magenta brown tan salmon black light grey (light gray) grey (gray) dark grey (dark gray)
Note: either spelling of grey/gray works. Added actually usable buttons, pen size changer, better colors, and a movable marker. I had a sick-ass thumbnail but it got deleted again because it was game play and I just made an edit on accident :P I'm not going to make another as this was the third time.
