I've read this tip several times.  I experimented with it last night, and the
difference between blocking and not blocking the sensor was minimal.  My light
sensor must not bleed much light directly across.  Perhaps I'm doing something
wrong?

Re: directionality, I've found that a black 1x2 beam works well to localize the
sensor, and if you put a black connector peg in there it can look right past
bright light sources and see dark objects.  This would probably work well in
conjunction with a laser pointer.
