I haven't seen the app, but a really good fog/water maker is Perlin Noise: http://freespace.virgin.net/hugo.elias/models/m_perlin.htm http://freespace.virgin.net/hugo.elias/models/m_perlin.htm There is a faster implementation of it, as perlin noise is pretty expensive, that get's used a lot in game design.
