Not sure if you mean a terrain generator, I have a couple of really sad
ones on my site. (URL below.)
Try using DejaNews to look through comp.graphics.algorithms there's a
few threads in there about this.

No. BUT can't be too hard to write one, can it?? Here's how I'd approach
it.

Try storing two palettes in arrays or structures or whatever. A and B.
Use the first array A to hold the original palette.
Copy this to the second B array.
Then set the screen to use the second B array as a current palette.
Then write a function to decreas this B array to 0.

void palette_fader() {
int i;

for (i=0 ; i<256 ; i++){

 if (cur_palette[b].r > 0) cur_palette[b].r--;
 if (cur_palette[b].g > 0) cur_palette[b].g--;
 if (cur_palette[b].b > 0) cur_palette[b].b--;
}

 vsync();
 set_palette(cur_palette[b]);
}

Dunno. I don't use progects in Rhide.
