Great looking effect. I'm a huge fan of photoshop filters and recently got the freeware L'amico Perry filter called Luce (which is Italian for "light", pronounced "LOO-chay"). I couldn't find a US site now, but did find one in Germany hosting on the attached link. For doing cool looking nighttime scenes or for Ray Traced underwater scenes "Luce" can save you hours of 3D computer processing time if you tried to do the same thing in Bryce or Vue using Volumetric Lighting.
