I don't think "snap" is really what I am looking for.  Sometimes
when the viewer button is depressed part way the bulb does not
light up completely, but that reduced intensity seems to increase,
not decrease, the golden/orange glow of the scene.  So the effect
seems reversed with the projector.  Why the difference?
