A window of opportunity

Ok, for the second year in a row I've ended up with a room that has very little sunlight and only one window.  Even though I couldn't do anything about the first issue, a change to the second ended up to be possible, well with a bit of imagination at least.

I had loads of photographs and needed to think of a way to display them so hey, why not combine my needs and make a window out of photos I thought. This is the turnout of this master plan, a window to my memories: 

Naturally I had to include a tree, had to be done.
