Dunno why my previous comment was removed. Trying once again:
If I were to do it again, I would remove the paper that thing is resting on, and show that circuit which is powering it.
Support the led on a transparent sheet
A neatly drawn circuit diagram underneath
Slide the circuit underneath to make the LED light
Pull away the paper to show the circuit, and make a slow pass again
Maybe change the music to something else.
