For the record, the eval_pigment technique was also discovered by Fabien
Mosen and published in the French-speaking POV group last February (in fact
Fabien has used it for his current IRTC image). I planned to add it as an
option to my own grass macro, but due to lack of time (and also because it
can only work using unofficial features, something I've tried to avoid when
publishing macros), it's been gathering dust on my hard disk since. I was
quite happy to have seen it discovered again by Samuel, and with very
impressive results, because this technique has really great potential (like
many things based on eval_pigment or eval_pattern) It just has to be worked
on to be made 100% practical. I'm very confident it can be done.
