[Tex/LaTex] Drawing a partitioned set with TikZ


I'd like to create a graphic of a set partitioned into subsets of various sizes/shapes/colors. (I'm trying to show a set partitioned by an equivalence relation into disjoint subsets, i.e., the equivalence classes).

I was hoping to find something on http://www.texample.net to give me an idea of a good method, but I'm having trouble finding any examples. Does anyone have any suggestions?

Some improvements to add colors are necessary.

\draw[clip] (0,0) circle (3cm);
\foreach \a in {20,60,120,180,230,250,310}
\draw (-1,.5) -- (\a:4cm);
