I don't know if this is within the rules of 's October 2013 Tweakfest challenge. fav.me/d6ot6sk I had a hard time picking parameters, so I picked two sets and fused them together. Here's the offspring!
I used 's sta.sh/01rshymhqy9i for main formula and outside colouring algorithms and 's for metallic textures and his use of different merge modes. (sorry, Jimmie, but Slope is a pain in the derriere to work with )
Params are here: sta.sh/05ag7a93w9h
