Each window represents some part of his life - hobbies, interests, work, play, family etc. and a private joke or two best left that way!
It took a long time to collect all the little bits to put in this. I suppose his birthday has been at the back of my mind all year as quite a few of the pieces are from car boot trawls over the year. I altered most of the pieces in some way, and made some up from Fimo. I was particularly pleased with the altered plaster head Borg (he's a Star Trek fan) with fimo headdress and resistor. Because resistance is futile...
Some of the references were a bit too subtle for him, so took some guesswork on his part and explanation from me. Like the L, T ans S. He couldn't place that, so had to explain that was the initials of me and our 2 boys! Jeez.
Anyway, he loved it, so that was good.
