Pretty cool looking one at the Dallas Guitar Festival - white back, faded charcoal finish (sans rainbow).
I had never consider this model before, because the rainbow is a little much for me. But, if they do some more one off colors - quite an easy way to get a 57/08 equipped McTrem (which to me is very appealing)!
Let's see some more of them!
My apologies for not having pictures of the one from the show. I forgot my camera...
