Why not? Fractals exist in all dimensions. Now, find its fractal dimension...
Has anyone tried to generate such fractals? As the phenomenon is 4 dimensional
this could generate interesting animations: "fractal animations" :) Of course
there are limitations: most of the current synthesis techniques are already 
too expensive for 3D phenomena. But, with a couple of Crays...

cheers,
