you could say pitch-syncronous granular synthesis is roughly 
equivalent to motion pictures. (i know this is arguable but)  they 
both use a frame rate that is too fast for us to perceive the data as 
discrete events-- therefore it causes them fuse into continuous input.

a system that did spectral fusion in the light domain synthetically 
would be interesting though.
micro-optic light clusters? it certainly sounds cool.
The thing is, granular is a successful technique because it exploits 
the duration that it takes the human auditory system to attach pitch 
to a sonic event.  Are there similar thresholds for vision,
and are they in a reasonable enough time frame that one could 
manipulate them in a controlled way?

As far as treating a digital image: I'm thinking it would be 
difficult to apply this technique to something static, granular 
synthesis is very much based in the time domain.  I'm often wrong 
though. :)

does anyone know if  there is software that gives very fine control 
over specific frequencies in the light spectrum vs. the time domain? 
if so, we could try to write some granular functions for it.
