Or you could put a large lined paper bag over your head with holes cut out for
the eyes, and then have a small grain-of-wheat bulb (do they make those any
more?) powered by a AAA cell through a variable dimming resistor to create
various levels of ambiance inside the bag while the room outside was totally

If you do that, please get a picture of it. Wikipedia is going to want it for
the "Kertesz Effect" entry, and I can't think of anything that would define it
better than someone sitting there with a paper bag over their head.

The newer panels seem to be going to 10 and perhaps even 12 bit resolving
power, which will tend to minimize that stepping effect. I know 10 bit panels
are already available in some pricey home LCD sets. Increasing the bits is the
only way to make digital anything approximate analog everything.
