This video was produced by rendering the following 489 bytes of code with POV-Ray:

About

This Video is part of the POV-Ray Short Code Contest #5 which was originally published by Paul Bourke in 2008. This page shows a new re-rendering of the original POV-Ray source code at a higher resolution, although here and there some miniscule syntactic changes had to be made to the code in order to get POV-Ray 3.7 to parse it.

Author's Comment

All wavy water effect is made by normal, the real form of the object itself is quite simple, just lathe of one segment Bezier curve. Better rendered if alpha is off. (seems to be a feature of POV-Ray 3.6.1 -- if alpha is on then phong highlight is clamped and looks not as bright as when alpha is off)
