1) Blinn wasn't talking about double buffering - he was talking about double
*framing* - the process of rendering the scene at (say) 30Hz on a 60Hz
display.
2) I know (of course) about the obvious artifacts like fast moving objects
appearing as though they are duplicated (or triplicated at 20Hz, etc)
- that's due to a simple physiological effect which is easily explained.
(If you'd like a simple explanation for this, let me know)
What intrigued me was that Blinn seems to be telling us that the brain
somehow interprets this update rate/video rate disparity as if the object
is moving faster - even though it covers the same distance in the same time.
That is a most remarkable claim - which (if true) should cause us all to wonder
whether the practice of running simulations at 30Hz is as valid a cost cutting
measure as we all currently assume it to be.
