I accidentally fixed my evolving fractals sever at some point. Strange how that happened. I don't know what I did or when, but it works again.
The applet is viewable at fractals.wikidot.com/
let me know how it works for you, and what you think about it.

You're welcome, and thanks for providing such nice example of jungle terrain with streams. Some day I'll have to try doing streams.
You're welcome. Your tree may end up inspiring many a forest; I like your approach, and something similar may someday end up in my planet generator.
heya, about your posts on various forums about subpixel accuracy, googling for that term should reveal exactly what you're after 
the basic idea is to draw your accumulation "dot" at real-valued co-ordinates, doing a floor and a ceiling for the lower and upper integer bounds respectively, then at each covered pixel using the fractional offset to blend between the 4 affected neighbouring pixels to add to the current integer pixel location.
since gpus do pretty much exactly that (bilinear filtering), you basically make a floating point backbuffer and pass a whole bunch of additive quads to opengl/d3d, letting the gpu do the nasty business of clipped subpixel rasterisation and accumulation, since it typically has several hundred gigabytes of memory bandwidth and hundreds of megs of unused memory for such buffers. the cpu is free to just make point lists...
