It can be simulated, but only on direct viewing through the prism or 
other transparent object.  In other words, you won't be able to do
the album cover from "Dark Side of the Moon".

There's a fairly good treatise on modifying POV 3.02 to do dispersion
effects at http://www.newcolor.com/darenw/dswpov/disp.html , though I
wouldn't recommend trying it unless you're relatively familiar with 
the guts of POV.  There's also an include file somewhere that simulates
dispersion, also for version 3.0x, but I don't have a URL for that 
handy.
