Cool Image on that site. I had no idea water reflection was so hard. I had an idea though. If you had a texture you wanted to use and you had a decent paint program that supported layers you could: 1. open that texture 2. save it under a new name so you don't mess up the teture you like 3. make a new layer over the texture and ensure you ar working on that layer only 4. arrange to fill that new layer with a gradient fill from dark to light where Dark = BOTTOM and Light=TOP 5. Now using the layer control palette you BLEND the tansparency of this layer to the one below it. There are a lot of different methods for blending supported by Paint Shop Pro 8, I have no idea about other programs. 6. merge all layers as soon as you get what you want. I do reccomend trying severl different blends and numbers of transparency before puttin in your program. --Rook

There is one on that website Swift posted a link for.

www.texturemaker.com is a great tool for making textures, and can also generate caustics.

I guess it wasn't obvious enough why I posted that link!
