I quite enjoy people who post pictures oblivious to what is in the background. There was a recent French posting where part of this 'Wall of Light' as Denis referred to it as, was showing. I asked for and received these pictures showing his interesting use of the glass multipart's.

There are just some things that you can't do with porcelain, but a big chunk of mud will hold a boat steady in a strong current while glass would let it drift.....
