We spotted the various Doctors Who (without masks) and the masks of US Presidents etc.
But there's lots of other Easter Eggs. I must ask my Eustace about the Bopamagilvie for example. The Interocitor reference should be obvious from This Island Earth, but how many know that that's part of the Attitude Control System for several satellites? They had a component that acted as the controller, as well as doing a few other things, so they called it an Interocitor. (No, it wasn't Ryberg electronics).
A lot of the folks at JPL and other places where those systems were developed were also fans of the classics.
As an Australian, who met A Betram Chandler on a number of occasions, I'm aware of the Mannschen drive. The Moebius coil could be from Tesla, or possibly a part of the Necrosope.
Only met him the one time, at a Westercon around 1976 or so. Nice guy.
The main usage of a Moebius coil that comes to mind would be in Keith Laumer's "Imperium" novels, though others have used the term since he first did in 1962.
