Heh. Just watching the mayday episode with the resolute bay crash, and they have an animation explaining ILS, only they use the antennas at the wrong end of the runway (effectively the back course localizer) :)
speaking of animations, there were narrated animations in MSFS 98 (yes! that's the first sim i played!) which explains VOR, ILS, PAPI etc. Short videos but crystal clear, better than reading 2 pages of text.
