Basic Curl

Wanted to get back in houdini land for a bit. Had a little idea with some SDF stuff but then relizedthat my fundamentals of using attribute fields inside dops was a little weak so I decided to just focus on something simple first and not rush things. Found / rediscoverd some good tools and techniques. For some reason today I've been writing very short abrupt sentences. Maybe I just need another apple or maybe its because I had to explain some work stuff that I thought I shouldn't have to explain.
