My SimplyTweet Punch Card

I use GitHub to manage my code and I thought it's interesting to look at my commit activity for SimplyTweet. GitHub has an excellent tool for this called Punch Card. This is how it looks like for SimplyTweet: It shows the relative number of commits (rough equivalents of changes if you are consistent) performed across the duration of the project. You can see that 1. I am most productive (again, commit-wise) the few hours around 12am and 12pm. 2. I am least productive on Fridays. 3. I seem to be slightly more productive during midnight than noon. 4. I work on Saturday nights. 5. I work on Sunday nights 6. I work everyday. Does anyone else has Punch Card graphs they like to share?
