To start, click Record. Then draw something. Use the Left and Right arrow keys to change the colour, Up and Down to change the shade, M to make the pen bigger and Space to make it smaller. When you are done, press Stop and then the Green Flag. Then click Playback to play your drawing back!!
This was made by HD123 - all I did was add a menu and make a few more changes. Most of the scripts I didn't even understand!! Anyway, enjoy, and make sure you check out HD123's projects!!
