I wanted to do something completely different, and came up with this scene :)
The plane as well as the sphere are failed iso-surface tries (for the same
object i wanted to create), but the sphere looked like some evil face to me
so I thought I post it here. I only changed the color map from the original
try, and wanted to try the focal blur feature. A mistake in the color map
clipped the top part of the lower iso-surfase to white, and the bad focal
blur settings makes it almost look like fountains :)

render time = 40 minutes on p3-933
