Goodness!  I feel like I was just in an episode of Star Trek with all that talk about photons,  LOL  There were words in there that I have to look up, hehe

Is that tutorial for Poser or for some other program?

I think my bride's tiara will be made of pearls!  It seems easier :)

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
