Tecktites from Greek tektos, molten) are natural glass rocks up to a few centimeters in size, which most scientists argue were formed by the 1mpact of large meteorites on Earth's surface. Tektites are typically black or olive-green, and their shape varies from rounded to irregular. I really enjoyed designing with it.

I'm too tired to do more tonight. I did take another picture of a black raven with a ruby eye. Tomorrow I'll check it out and see how well it photographed.
