High!

As I want to have floor tiles with slightly disturbed reflection in my 
Port Whatmough villa, I started to play around with the blurred 
reflection hack described here: 
http://wiki.povray.org/content/Knowledgebase:Language_Questions_and_Tips#Topic_13

Slightly disturbed reflection works quite well (see my test table 
below), but I wonder how to achieve that strong, smooth blur I've seen 
in so many scenes during the last years - using a large scaling factor 
for the normal (e. g. 1000) yields weird results with high turbulence 
values, while using small scaling factors like 0.001 gives something 
remotely resembling my notion of blurred reflection, albeit still quite 
grainy.

Should I try an even smaller scaling factor (0.0001 or so) and/or using 
stronger anti-aliasing?

See you in Khyberspace!
