In this animation I have tied a Point light to the ball that is traveling up the spiral on a Contour Stroke path. As it moves in XYZ space the light is focused the ball's diameter toward the viewer.
The next step is to orientate the lights origin a selectable distance from the Z-Axis of the selected object. In this way we can have a light that can rotate with the object making a spinning light! I can't wait to try that. Then maybe multiple moving lights might be up my sleeve.
Thanks for viewing!
