George,
A goodly while ago Mark Sanger made me see that wood, at times, is only the carrier of further work.
You've turned that back on itself, making the further work become a necessary part of the wood to reveal the hidden picture. I can see the abstract designs you created at the start of this journey with wood and glass, but it's already come a long way, to now creating a whole picture by the addition of a single additional image in the glass.
Are you bringing this to the club tonight?
