DarkTree Potato Skin

// January 23, 1999: By Ron Wolfe. This is from an actual potato 
// skin that I studied one evening just for an exercise with DT. I 
// imagine this tree might also find some use for other surfaces 
// than potatoes :) No, life is not that boring - it just struck me 
// as an interesting texture. Another interesting (to me) method 
// that I use for Darktree texture ideas is in games. Just start 
// wandering around in Riven, and there's enough textures in there 
// to keep you busy for a long time :)
