Does anyone have experience on that?

I recall having played with both the interpolation of color matrices and
transform matrices using SMIL in the past. I will try to poke around and see
what experiments I might find. 

The only one I see right now is
http://cs.sru.edu/~ddailey/svg/feColorMatrix.svg (the rightmost example and
working properly in Opera and FF -- Chrome and Safari? Not so much) but I
built a couple hundred filter examples for our recent book, (and of course
one animates filter effects! -- it is as natural as replicating snowflakes)

What I remember is that fiddling with animations on color matrices was no
trickier than fiddling with color matrices in the first place -- it takes a
while to get one's head in the zone, but then it all makes sense and one
feels a small door opening in the corpus callossum .
