I can't find the epic thread in which the existence of clear metal collar stays was postulated.
Nonetheless, that possibility may become actual -- Oxford scientists have, apparently, created a transparent form of aluminium: http://www.physorg.com/news167925273.html
The bad news is that the transparency only lasts for about 40 femtoseconds, and can only be done in a spot with a diameter of less than 1/20 the width of a human hair. But we're getting there!
... isn't it sad that, upon reading this, the first thing that I thought of was SF?
