There is a whole article on Radiosity in a 'recent' issue (1987-89?) of
IEEE Computer Graphics. 

Basically, (from what I remember of it) Radiosity works by treating all the
surfaces as having thermal radiation. I would imagine that that would be
more compute-intensive than ray-tracing, but would produce more realistic
effects. For instance, shadows would be soft, for instance. Something
I would like to play around with someday.
