Today I tried to find a suitable replacement for my Lego water:
 <web.49472c24399f7e1d778c150@news.povray.org>

I could not. I was able to make some watery chrome.

I'd love to see someone find something better than f_ridge for the Lego pool. I
doubt anyone can.

If you want to try, legoworld_pool.pov is in the legolib zip here:
http://home.earthlink.net/~openuniverse/


here's the norms you posted:

global_settings {
number_of_waves  1
RippleNorm 01
Bigripple 02
Smallripple 03
}

global_settings {
number_of_waves  2
RippleNorm 11
}
