I was looking over some search results regarding general patterns, and came
across some work regarding a crazed enamel/lacquer or spider-cracked glass that
I was looking to somehow implement.
It looks like it might offer some new approaches to the ivy-generation macros
that were written, and provide a way to texture the isosurface leaves that were
discussed not too far back.

Perhaps someone might find this interesting enough to start implementing in SDL.

Quite interesting and worth thorough investigation; however, what as to 
eaves previously mentioned, I strongly suspect that Perlin with minimal 
filtering (probably minimal. I mean sorting) may go.

Works fine (albeit slow) for me, regardless of sanctions.
