Hey it was an easy one to get confused with.  It certainly is
counter-intuitive when comparing phase with something like a normal which is
what I was likening it to.  With a normal (and no map) the phase keyword
acts like I was expecting it to.

Confusculating, but it all makes sense.  Now I can finish that little
animation I started a couple of weeks ago.  It's just a rod in wavy water,
but I'll put a link up when I've got it half-way decent.  MegaPov is
crashing when I try to get glass sides on the container I'm using, but I
think I'm getting some effect of csg randomly choosing one pigment over the
other, so I'll have to go over my csg differences before I get it working
properly.  My next door neighbors recently bought a fish tank ... isn't it
amazing how you look at things in terms of ior and photons when visiting
people!

Thanks people,
Lee
