There are glasses which increase their darkness in the presence of greater light. But they take some period of time to darken, and they darken unanimously across their surface. I think it should be possible to make some kind of material which would only blacken out distinct light sources (like the sun), from any angle, and preserve a florescent quality across the rest of the surface, or other angles. This would be invaluable to windshields as cars drive towards a sunrise or sunset.

Ignorance?
What is the source of ignorance? Is it really a smaller part of some other kind of human character? Or are we just ignorant? Should the limitation of knowledge be a justification for crimes of all types? Or should it be a call to a more humble kind of human progress?
