- You're talking about 'Fractals' and 'Chaos theory'. They are inter-related.
- Thr triangle thing is easy to duplicate:
- Take any three points, and label them 1, 2 and 3.
- Now pick a random 4th point. Pick a random number 1-3. (you can use a die for
- this, just use 1-2 as 1, 3-4 as 2 and 5-6 as 3). Mark a point halfway between
- your 4th point and the point indicated by the die roll. Roll the die again.
- Mark a point halfway between your new point and the point indicated by the
- die roll. Keep doing this a whole bunch of times. What you get is a picture
- of a triangle with a bunch of triangular shaped holes in the middle, all in
- a nice regular pattern. This is called a Serinpisky (misspelled, I know)
- Gasket. What the interesting this about it is that the closer you get to it,
- the pattern remains exactly the same, no matter how close or detailed you get,
- the pattern will remain identical. There is another sort of thing along the
- same line that produces a 'butterfly' pattern (though not a self-repeating
- pattern like the gasket), and yet further types that produce odd mathematical
- pictures of blobs and odd shapes.
- The point of all these are that while the end pattern can be ascertained, and
- will always be the same (triangles, or butterflies, or blob-like things),
- the individiual points that are chosen cannot be predicted to follow any
- sort of pattern.
- You've seen fractals a number of times without realizing it- this same sort
- of mathematics is used to produce the computer graphics for movies. The
- 'Genesis Device' scene from one of the early Star Trek movies is a good
- example of this.

- Further discussion is re-directed to sci.fractals, though if you have any
- questions, you can mail me :)
-
- For those who know about fractals and chaos, please don't pick on the number
- of obvious holes- its a general overview thing :)
