I don't have one with spider
I don't have one with spider webs (though I believe it), but I thought I'd share this one--taken in the new office he moved into last summer. This was right after he moved in, so the piles hadn't had time to build up (though they did). For as chaotic and packed with stuff as his other office was, I always found it very comforting to work in. It was a reminder of all the different things he was interested in, which was reassuring to me that the world was rich with things to learn about and if someone as smart as he was never bored and could always find something interesting and new to think about, then I and others could too.
