Originally for the WTC: Mondo Tubular challenge in the dA Apophysis group. I started with a script by shortgreenpigg and tweaked settings for roughly an hour to get this result.
Remember kids: Scripts just give you a place to start. If you aren’t spending time changing settings and playing with it, it’s not really your own work!
Apophysis 3d 2.06, color adjustment in PSCS2.
