I'm working with some L-systems and I have a question.

If I wire up a polywire SOP to a l-system and wish to have my l-system get progressively smaller in width, what is the best way to do this?

I hit upon the idea of mapping the $LAGE value to width but that gives me the reverse of what I want, with wide tips and narrow trunks.

What is the best way for me to invert the results of $LAGE? I'm experting with normalizing $LAGE and inverting that but to no avail. Am I missing something obvious?

Doh. 1-$LAGE will work fine, I have to clamp the resulting value so it never goes past a very small positive value. Doh. ops:
