It is supposed to be leaning against the wall. The edge of the cross is 0.4
units from the wall and it is 1 unit high. I had hoped to make the shadow
illustrate that. I'll work on it.

I'll work on that. The book is meant to be a smaller leather bound style
book, but it's a bit thick here.

I'll keep upping it. I had no idea I had to go so high to make that flame
visible.. then I guess the next step is to make it look good ; )

The floor isn't visible. It's a shelf with some darn near invisible braces.
The pattern on the wall is inexplicable. There are two crackle patterns with
the same densities, one of which has transparent bands in it, and the
surfaces are less than 0.1 units apart, but the patterns are vastly
different. I'll have to rework those into one surface.

Thanks for the advise. I'll try to get that scale problem fixed

Thanks, for some reason the paper causes MacMegaPov to crash when it draws a
pixel for that paper on my G3, but on my older iMac it works. I suspect it
might have something to do with the tga file and the transparenct channel.
