[Haskell-cafe] Animated line art

So, the muse has taken me. I'm going to attempt to produce some animated 
mathematical drawings involving lines and curves.

Gtk2hs has a Cairo binding that should make rendering the stuff fairly 
straight-forward. So no problems there.

Now, what I *could* do is write a new Haskell program for each drawing I 
want, hard-coding in the necessary imperative loops for updating 
coordinates, looping over multiple lines, etc. But that wasn't be very 
Haskell, would it? ;-)

It seems that the "correct" course of action is to design a DSL for 
declaratively describing animated line art. Does anybody have ideas 
about what such a thing might look like?
