Ferns - Static view

This deviation needs a bit of explanations...
I still plan to participate to the 2008 Ani-Jam, although the (extended) dead-line is quickly approaching.
I chose the computer generated animation way because I had no material time to do hand animation for this project.
Since I recently discovered the Processing "language" (actually a graphic layer/library/environment around the Java language), I chose to use it to do this.
I made a proof of concept sketch on paper, defining how I would build a fern: a trunk made of successive segments, two start of branches per trunk segment, branches made of successive segments too and two leaves per branch segment.
By varying the angles (relative to base and previous segment), widths, lengths and colors, I thought I could make quite varied kinds of ferns.
I had a bit of trouble building the base algorithms/structures (classes) but finally it is here.
Well, almost. I planned to make them evolve along a timeline, to animate them. Initially from very young state to fully grown.
I still haven't reached this part, so I thought I could at least show the static renderings I have, as kind of appetizer.
Since the deadline is in (less than?) two days, I might just do a translation (pan) with fixed ferns. Better than nothing, I suppose. But I will try to do better, anyway.

Note: as far as I know, currently deviantART has no category for computer generated 2D art, except for fractals. These ferns are not fractals (in the strict sense), so I have put them in a 3D category. Which is not incorrect: 2D drawings can be seen as 3D with a Z dimension (depth) always null...
