HHGTG book 5 in the increasingly inaccurately labeled HHGTG trilogy had
this
great moment in there where the guy in the spaceship realizes that the
robots keep falling out of the hole in the wall where the
asteroid-collision-detecting 
device was neatly knocked out by an asteroid.

Oh wait, that's unrelated.

Maybe look up recursion in kerningham and ritchies introduction to c
programming manual
instead.

There is a company which does CFD calculations of heat flows in computer
rooms.
This of course needs powerful computers to run, leading to more heat
load, leading to runaway positive feedback.
