I thought this was interesting because you essentially print each frame of the animation of the individual characters, and the movement of the characters in space is controlled by the strobe frequency and is not fixed at all.
@xTheBHox Or, perhaps more accurately, the strobe AND the rotation speed of the wheel (since if they're out of sync the frames will shift).
@xTheBHox, @mdsavage Yeah, synching something like this up seems like it would be a total pain! (Can you write down an equation that relates the strobe rate and angular distance between printed frames to the rotation speed, assuming you want the observed objects to appear stationary? :-))
