IMAGE DESCRIPTION:
	When
I'm at work and need some dry glassware, I open up our oven, and 
	this is
what i see... the pieces of glassware from left to right are
as
	follows:
		10ml graduated cylinder
		50ml erlenmeyer flask 
		25ml
pear-shaped round-bottom flask
		(in front) syringe
DESCRIPTION OF HOW THIS
IMAGE WAS CREATED:
	The actual description of the objects is quite simple,
but it took me
	a lot of time to get the shapes of the objects (at least
somewhat)
	correct. All three large glassware objects are lathe objects.
	

	As a novice, it wasn't entirely clear to me how to properly get the

	*white* labels onto the glass. On my first few attempts, the antialiasing

	of the text was very obvious, and the glass was being darkened by
	the
image map. My final solution was this:
	 
	1. Use a grey background for the
text/lines
	2. Use a large font size (about 50) so that any antialiasing at
the
	   edges of the letters will not be seen. save as gif.
	3. In an
image-manipulation application (i used graphicconverter),
	   edit the
color table, changing the background (grey) to white.
	4. In povray, make
the background color index the transparent one.
	 
	Anyhow. Unfortunately I
didn't get to spend a lot of time working 
	on the oven walls/shelf, so
they look pretty weak. The lighting is
	all wrong, and the walls really
should have a stainless steel look, 
	which really doesn't give as sharp of
a reflection as I'm getting. 
	Anyone have a good stainless steel texture?
:)
	 
	If I actually managed to get the zip file looking like a zip
file:
	The zip file contains the following files:
		text file: oven.pov,
syringe.inc, flasks.inc, area.inc
		images: erlen50b.gif, gradcyl7b.gif,
syringe_knurl.gif, pear.gif
	 	 
	I'd be more than happy to give the image
to someone in a different format,
	or give the source code if the zip file
isn't working.
