I don't know if infinity infinity is further than infinity with regards to
projection but I would guess so (with the associated eyestrain of course).
The reason I say this is because as a few P3D list members might remember,
Bill Ewald (spelling?), keynote speaker at Rochester , had talked about
this. He mentioned an amusing past time of looking farther than infinity!
This was also subsequentally discussed on P3D (if I recall correctly!).

Now those that remember this better can refresh my memory, but what he
had said was that he used to mark on a window pane a separation of
slightly more than 2.5 inches so the eyes would diverge freeviewing these
marks. Now the neat thing about all this is that looking up at the stars
while freeviewing the marks, the stars would seem closer than the marks
on the window! Looking past infinity!?! ;-) Has anyone else tried this?
