With this scene you can record the movement of a tracer (draw a picture or write text) and then play back the original movements.
It started out fairly simple, but then I kept adding features to it (ability to change color, etc) and now it might be a little too complex. Anyhow, play with it and see how you like it. There are likely some bugs, so just tell me about them and I will probably ignore you. 
Instructions are in the scene, but here is the simplified version:
Touch cursor to the white box and press R key.
Draw your picture by slowly moving the white box around.
Change color by pressing number 1 through 6.
Stop recording by pressing S key.
Press 0 (zero) key to reset the counter (and press Ctrl key if you want to erase the trail).
Press P key to playback your masterpiece!
When ready to record a new drawing, press the Return (Enter) key.
