@Vincent: So you're a lucky guy, how can i obtain such a low retinal persistence too?

I managed to take some photos of the effect:

The others are stills from clips taken while moving the cam around to simulate the eye-movement.
In all cases the tv-display showed still pictures!
You can prove the effect too by just holding a digicam towards the screen (again while showing a still picture on the screen) and checking if the colour-histogram is moving cyclically. If the cam doesn't have a histogram-feature, you can probably see the picture getting green or blue on the lcd of the cam. If not be sure to check different exposure times.
