When I was at the Phoenix Comicon, a girl came up to me on the first day and asked me if I'd sign this present she was making for her boyfriend: a papercraft d20.
She was taking it around the con and getting a few people she thought he'd like to sign it for him, and I was on the list. I needed to run around in a circle the way my dog runs around in a circle when she's excited for a biscuit, because I was just blown away by how cool this idea was, and how cool the whole thing would be when it was assembled.
I'm not sure if you can see, but I'm next to the Superman "S". I wrote, "Hope your birthday is a critical success!" Because, um, well, if I have to explain why, I don't think you could fully understand why this is one of the most awesome geek gifts ever delivered.
Here's the catch: I wasn't allowed to mention it on my blog or on Twitter, because I guess he reads them both, and his birthday was after the con. Since it's been delivered, and the images are online, I think it's safe for me to go ahead and share this, in the hopes that other boyfriends and girlfriends of geeks will do something similar. Speaking as a gaming geek, this is one of the most thoughtful, unexpected, truly awesome things one of us can get.
