Dave Addey’s post about the typography in the movie Alien is worth a read from top to bottom, but my favorite part is Semiotic Standard system of pictograms. 

These icons are the work of cinematic design legend Ron Cobb. He named them the Semiotic Standard For All Commercial Trans-Stellar Utility Lifter And Heavy Element Transport Spacecraft.

Cobb’s icons have had an enduring impact on the visual design of science fiction movies since the 70s.
