Here are the POV-Ray prism and SVG files unzipped. I still don't know quite 
what went wrong with the zip.

Your height fields benefit from a smooth edge whereas the prisms leave a 
very sharp.
I notice that converting your images from png to jpeg brings your images 
down to about a quarter their size. Although jpeg is lossy it doesn't seem 
to be detrimental to the result.

I also noticed that the two sets of glyphs differ slightly in their outlines 
I don't know which is most authentic or even whether there's any consistency 
in the TV shows and films.
