The Golay processor has been around for about two decades; it's a
hard-wired hexagonal processor performing logical operations on boolean
image data.  I believe that various medical image processing
systems offer shrink/expand cycles for image overlays that can be
similarly programmed, and there are both software languages and
parallel-processor projects aimed at permitting easy specification
of parallel local operations on image arrays.
