Unrelated but might trigger a few memories on here: I managed to get a copy of povray on one of those freeware cd-roms that computer stores often sold for a few dollars (since the internet wasn't a thing yet and getting it from compuserve was tricky). I think I sunk years of my life rendering beginners geometry, all the usuals: snowmen (spheres!), tables of still life geometry, basic animal characters and lots of snow scenes or rippling water sunsets (povray was particularly good for these.)
