I'm not disagreeing, but this is only one small, almost insignificant 
piece in the development of POVRay.  It would seem out of place if it 
was the only little tidbit there.

If I thought there was a market for it, I could write a book on the 
origins of DKBTrace and POVRay to cover little things like that.  For 
example,

	- the original inspiration for DKBTrace
	- using calculus for quadric surfaces
	- the pesky black speckle problem
	- the pain of CSG
	- solid textures and where they came from
	- refraction and how to get it wrong
	- calming down the waves pattern
	- layered textures
	- building the roman towers
	- early images
	- introducing spheres
	- Phong specular highlights
	- the transition from DKBTrace to POVRay
	- early work on POVRay
	- version control tools - ZIP, ZModem and 2400 baud modems
	- POVRay 1.0 at SIGGRAPH '92

Maybe I'll toss around the idea.  I already have a science fiction book 
I've submitted to a publisher.  This could be a fun book to write. 
Would there be interest in a book like this?
