Okay, this stuff looks perfect. Thanks so much.

I was thinking about the different materials i could use. I think
clear acrylic would be very cool but it probably will not cope with
soldering unless I am very quick.

I started thinking glass would be very cool but working with it may be
difficult. I have a milling machine so if I can find the correct tools
then I might be on to something. I suppose I can cut the glass fine.
What need is to find some way to drill the holes. Also i need to be
careful about cracking it with localised heating when soldering. Maybe
if I used a solder paste and heated the whole board this would work okay?

Does anyone know if I would get away with drilling glass with a
standard tungsten carbide drill bit set. The spindle speed of my mill
goes up to 60krpm. Be nice to hear of any experience before i risk
destroying some drill bits trying.

Anyone have suggestions for other cool materials? Maybe 'Mother of
Pearl Shell'. All just thoughts at the moment but could be pretty cool.
