sero2 ran var curve edisc dc_crackle sphericalN

From the notes to the script by Michael Bourne - "The standard one, creates lots of tunnel looking images (which is what I was after) Adds a random final transform, then a curl, and and edisc." I added a dc_crackle, a foci3D, and a sphericalN. I rendered it in jwildfire in HDR; converted it with luminance hdr.
