During the last storm we had, I did stuff like that with the blue light on my dad's RadioShark. :P But I moved my camera instead of the light source. And I made shapes. (The star turned out the best.) But it was hard to get the hang of because if you move your camera up and to the left, the light will look like it moved down and to the right. :P
