Building the scene
Finding a base for my textures was no problem since I have quite an amount of pictures and stuff stored on my computer. During the last few years I've looked everywhere on the net to find any usefull texture. And I must say that there is plenty to find these days, even for free. And with my 2 megapixel digital camera I can shoot whatever I want.
For the wood I just took a good, old looking plank texture, played around with the colors a bit and made it properly fit on each object. I hate distorted image maps. Added some grey dust on the edges for the horizontal planks, and that's it. The bumpmap is a greyscale copy of the original. Ofcourse I could have add different layers of displacements to add some detail but these planks didn't need that.

To create the old-looking metal structure on the screws and strips, I have used 3 different kind of texture layers.
1st layer - a procedural texture generator
2nd layer - a texture map
3rd layer - a soft gradient
No bumpmap on these.
* Caligari Phong Shader.
The adapters made of steel have no texture map. I gave them a dark grey color and because of the layered reflectances, pong and mirror, it gets that special half shiny metal-steel look that reflects light very brightly as soon as a lightsourse hits it's surface but at the same time can be very dark and reflects almost nothing in the shadow. These shaders combined produce a fine steel look.
