The details would have to be worked out, but the basics of my idea would
be to first make a distance-information render where every surface is
colored according to it's distance from the camera, then to use this
information in combination with a heat-wave looking pigment function to
blur surrounding pixels of a full-color render in a heat-wave style
pattern. Something like: blur=distance*heat-wavefunc.
