Twitter Stats gives you a graphical look into your twitter activity

Damon Cortesi was curious about his Twitter statistics. That is, since he had started using Twitter, who had he been talking to the most? When was he tweeting the most? And so on. He developed a sweet script that pulls down all your tweets and saves them into a comma separated file. Then his script runs some database kung-fu and produces some sweet graphs based on your twitter activity.

Best of all, you can run the script without giving up your Twitter password.
