Amazing textures! (Is there an echo in here?) I honestly did not know POV
had wood like that in it somewhere. Just goes to show what a far more
creative and motivated person than I can do. A posting of the wood textures
would be most beneficial to the less-than-skilled such as I.

Hi,

Thankyou to everyone who provided comments on this image. I'm adjusting
the model right now to take into account the improvements suggested by
everybody. I particularly like the idea of having a plaque on the
machine. This is delaying the render of the machine in it's full
sparking glory even further :)

However, on the point of the textures, I think I'm getting rather more
credit than I deserve - I'm afraid to say that the wood textures are not
procedural - they just use image maps :(  
I gave up on procedural textures after I couldn't obtain satifactory
results. If anyone is still interested, both a description of how I
obtained the maps and the texture with the image/bump maps is appended
below.

The wood texture was obtained by searching auction pages for images of
antique furniture, so  obtaining a detail of a small teak table. I
copied a section of the wood texure and adjusted it to tile neatly in
Photoshop. I then "dyed" copies of it to get appropriate colors for both
the machine and the table. Copying this, desaturating and adjusting the
curves gave the grain bump map.

So? You've taken the time and effort to create them. Your source of
base images is pretty neat, too :)
