Print your own "Hello, My name is" badge for attending conferences
I was lucky enough to attend the first and second OggCamp un-conferences, and was able to meet quite a few people I had gotten to know online. There was just one problem... how do you identify someone you've known only via forum avatars? A quick coding sprint later, I had a small PHP script that would generate you a "Hello, My Name Is" image that you could print out and stick on your shirt/laptop/etc.
