Help making a drawer where the player moves the paper actor and pen actor is stationery

I've been wracking my brain for a while trying to come up with a way to create a drawing game where the pen is stationary and the player moves the paper underneath. I've tried several different ways with varying degrees of failure! One version that came close was to create a large white square by tiling together a ton of small actors and setting them to individually turn invisible when they collide with the pen actor allowing a dark background to show through as "ink". But who wants to have hundreds of actors on a screen? Anyone have any ideas? Thanks!

Here is an idea, when the paper is moved, record the distance of x and y from the pen tip to the coordinates of the paper's center (subtract), every .1 seconds and have it record them in the table. The spawn the points or lines between those point values in the table in x and y coordinates relative to the paper actor.

Thanks! I'll give it a try!
