ACDFSM: interesting shadows, but a very ugly presentation. And you really should have asked me for my dll, as I did some fixes which finally allow a pretty good resolution for the sunshadows without any errors... It seems to have some problems close to the shadow casting objects and I am not sure about your bias, it seems quite high? But definatly good work, a nice readme and it seems easy to reuse

RayHairLightSoft: looks nice and clean and seems to be some good work, it just misses something to make it more special. It is kinda boring somehow.
Shadershowcase: sorry, but it weather shows a nice scenery nor any interesting effects. But I like the menu and the information panel and so on.
ShadeC: I would have prefered to see some textures and more of the water. Detailed textures most probably also would have hidden the low shadowresoltion and the resulting problems a bit. I like the refraction effects in the outdoordemo and the volumetric light. But the presentation is weak and it is missing somekind of an über-shader to make it really special.
Sea VTF: Very nice water and a nice presentation. Nothing more to say.
Tower on Planet: I love that stuff

Wavefield: some very good looking waves, great lighting, nice details like godrays and those animated, wet stones. Another very special thing about it is that the switch to the underwater effect takes care of the waves... The only things I am missing are some particles and underwatercaustics.
It is very hard to decide what to vote for, but I think I am doing the right choice

I btw enjoyed most of those readmes a lot. Very cool how much information some of you put into them.
