I took an interest in exploring order in chaos from a different
direction. I was inspired by a suggestion in a research report
that in the long run (enough iterations) clearly non-random
results appear. This first approach was simply getting the
process to work. There was no methodology in the report. 

Using the attachment as an example --

	It starts with an array 0..257 by 0..257 with all the pairs
containing 0 and 257 (the edges, boundary values) constrained to
zero. 

Step 1. Each of the other array elements, 1..128,1..128 are given
a random number between -0.5 and +0.5. 

Step 2. Then each cell is averaged with its nearest neighbors (8
neighbors + itself for 9). 

Step 3. Return to step 1, twenty times in the case of the
attached image. 

Step 4. convert the final array of numbers into triangles in mesh
object format. 

Setp 5. Render 

	It's a 19Meg POV source file if anyone is realy desperate. The
generating program is only 2k but you have to have Turbo Pascal
or download Free Pascal. (Go to Google.com and search 'free
pascal'. There are plenty places to get it.) Of course it is a
first attempt 

	All that aside, speaking of the image, the scale is linear, that
is 258 units on a side with the added increments of +/- 0.5 at
each step. Visually I see some extended patterns in the image. It
is also visually interesting but then so are the holes in
acoustic ceilings if you have nothing better to do with your
time. 

	Eventually I intend to produce an animation of this, one frame
per iteration (step 3). 

	/*Ignore the little thing in the lower left corner. I just
dropped the mesh into an existing scene file.*/
