Before there were SLR cameras they made polarizing filters equipped with a
smaller filter on a side stalk, which you could look through while rotating
the filter for best effect.  I have used clip-on polarizing sunglasses with
rangefinder and "point 'n shoot" cameras:  Hold one side in front of the
lens, look through the other and rotate for that neat dark-sky effect.  The
optical quality of the clip-ons isn't the greatest but they seem to work
acceptably.  The polarizer must cover the camera's light sensor (or you
must manually adjust the exposure accordingly) because even the best
polarizing filters transmit only about 1/3 of incident light.  You could
get a sheet of polarizing material (e.g.  from Edmund Sci. Co.) and hold it
in front of a non-SLR camera which is not equipped to take filters.
