The program only draws two lines: one that runs across the width of the screen, one across the height. But you can move these lines and toggle the color (black or white). You can also save to and load Pic6.
The download is available at calcodes.wikidot.com.
And, to kick off the release of this small program, I decided to have a contest for Line Draw pictures.
Best Line Draw picture
Weirdest Line Draw picture
Contest ends July 4th!
