rcb25 : Well I only have a 'floor' in my scene, no walls. To get the 'total white' effect just open the attributes for your persp camera, change under the 'Environment' tab the background colour to white.
The wires are really simple. Make a face of the shape you want your wire diameter to be (circular, square... as many edges as you like). Use the CV curve tool to create your wire path from the center of the face/s. Select face/s, then shift select the wire coming out of it. Use the extrude option box to extrude along selected curve with however many divisions you like. Don't worry about getting it right first time, just adjust the divisions in your extrude history and even the control vertex points on your CV curve history after its created to move the geometry. Hope that makes sense :s
