Just a little side issue here. I keep getting comments on the blog that I can't publish because the commenter's name and comment are rendered in a font that my browsers (none of them, and I have many) cannot render. If you are not having your comments published, then this is the reason.
Break in Transmission
The recent pause was due to an extended period of working abroad without access to my code and Povray sources. Normal service will be resumed shortly.
