I guess Alex already pointed out a good possible solution. I'd only
add to this the declarative animation support [1] already in SVG
(using SMIL), which adds the "temporal" information you might be
seeking about. :-)

(Apart from the above,) You could also try using scripting (for
example using ECMAScript - a.k.a. JavaScript - or other languages).
You'll *definitely* want to take a look at a tightly related SVG Wow!
demo [2]! ;-)

I'm assuming that "this area" relates to graphics and stuff and I'm
always glad to hear when someone with expertize joins the community.
Welcome and good luck! ;-)
