I finally ran into the same problem at high speed last week. Rats. With or
without an accessory light, the difference are just too small to deal with... or
at least trust. So I took off my nice, compact light sensor, and had to invent a
mechanical one. Oh well, I learned, and it seems to work. Still not 100%, but
it'll get there. And I could still potentially determine block color if I really
wanted to.

My program is growing bigger than it should, but I'm trying for kind of a
flexible, general approach, so there's more than one level of abstraction in
place. It finally seems to (mechanically) work (you remember, that's the part
that Matt grew on his own).
