My heart went wonk a couple days ago, I am trying to keep active and perked
up. Its been really nice recently. It is good to see you :]
You have to decide the source, its path, and the scale of gradient you are
going to use. (contrast) You need to flag the surfaces closest to your source,
and fathest away or hidden from it. The rest is practice and some technique
you coukd pick up in a pile. I hope someone can say it better.
