Jewellery from computerparts

On multiple websites I have seen 'geeky jewellery' on offer, made from computerparts. Since I am in the process of cleaning up my laboratory a lot of stuff which might be interesting to make into jewelry has turned up. I will have to make an inventory of interesting items and see what I can make with it.
