Call me a freak but I find I detect motion better off centre. If I want
to act like a robot and 'trigger' on some movement/colour change, I stare
off centre to the target. This staring into nothing in particular, apart
from less eyestrain, let's me switch off and flinch. Okay, I admit it,
I'm Robbie the Robot. I suppose one way to possibly emulate this is to
bleed the colour from anything off centre.
There's a certain je ne sais pas missing from 3D shooters. As 3D
shooters do not blur any of the screen, changes of single pixels
stick out like a neon light; the twitch technique works so well coz of
this. Fuzzing objects in the distance would add so much more. It'll then
be a case of "You can't make out the details not because you don't have
the CPU cycles or you don't have a high enuff resolution, your character
is short sighted."
In any case, take a look at the game Dungeon Keeper and take control of a
beetle. You end up viewing the world with a goldfish lense. Different
creatures have different vision. It's quite cool until you start to think
you really are a beetle.

I wanted something like this for a gui. The active window in focus is
precisely that, all the other windows look blurred. Not practical but so
what? :)
Both the above devices would work quite well to focus player attention, if
that's what you want. Blurring seems too CPU intensive anyway.
Especially 3D blurring - render the same scene again and again from
viewpoints up to r radius away picked by gaussian distribution. Just
another of those ideas which go in the "Ah, that'll be sweet but - "
folder.
[CPU intensive? Hey, just aim to release your client in 5 years' time
when there's even more MIPS ;)]
