Today is day 50 of my contribution to the 365Days Project on Flickr, where the goal is to take a self-portrait every day for a year. To mark this milestone, my contribution for the day was me flashing a "fiddy" hand gesture. This is unlikely to be any sort of real hand gesture used or understood by anyone, but it does handily spell out "50".
This is also marks the 50% mark of my participation in the month long NaBloPoMo. If you don't know what that is, and are unwilling to look it up on Google or follow a simple link, then frankly I can't help you.
