For dydactic purposes I have written a program that will recover the usual algebraic formula (in fact the formulas found by the computers are stored as sets of numbers representing algebraic operations and constants). Once you have recovered the algebraic formula for some interesting attractor you can try to understand how the formula produces the image and introduce interesting variations. As an example of this exercise there is a list of some of the simplest formulas found by my program.

What you do is a kind of "reverse engineering" and you can build now a data base of synthetized formulas to which you can apply the same tools seen before. Of course you can introduce in this data base the formulas that you already know with some parameters and play with them by animating the parameters or breeding them. Especially interesting is parameters animation since it shows the onset of chaos with beautiful animated images.

For research purposes you can try to classify the dynamical systems. This is done by building lists of pointers to the images. So you can have a set of dynamical systems with threefold,fourfold,etc symmetry. You can try to discover unexpected shapes that can be connected to new phenomena,etc. In general,it is hoped that through a process of visual thinking the researcher after it get used to the data base, can have a more clear idea of the data stored and discover interesting new phenomena. The normal statistical analysis should now proceed more quickly since we are no more searching in the dark.

Now in concrete how one can use these tools in a collaboration?

- Artistic use is becoming by now common : I cite only Karl Sims with its
show at "Centre Pompidou"(or was it "Les Halles" ) in Paris.
- Dydactic use by students
:using these tools means a concrete exploration of abstract
properties of nonlinear systems.
- For research purposes I have tried to try to understand where symmetry comes from.
