XY-plotter making the letter A (just motors)

This is two stepper motors controlled by an arduino for a school project. The frame for the plotter isn't done yet, so so far its only the motors moving. Notice how the motors move to make the shape of an A, where the left motor controls Y-axis, and the right motor controls X-axis. In the very end of the movie, you can see a drawing of the A that the plotter draws, ad tiny arrows on the A indicate where the plotter is drawing. The crossed out arrows are when the plotter just moves to position itself. The arduino cant multi-thread to control 2 stepper motors simultaneously, but I've made an algorithm to move the stepper motors little steps to one motor at a time. They look like they run simultaneously, but really they only move a little one motor at a time, and really fast.
