Quaid navigates the hazards of Shorts bodily functions in order to plot his escape. Twenty years on, there's something rather quaint about it. A vessel the size of a cell? With a pilot inside? Compared to todays innovations in nanotechnology, it's akin to using a tractor trailer to find your way through a corn maze.
