A few scripts to draw art to you commit graph on github.
The art to draw is defined in gendates.py, you likley want to edit it.
Then clone an empty repo to repo:
git clone git@github.com:you/somename.git repo
Next run doit.sh to generate the commits, It will prompt you for the end date of the art (In ISO date format).
Finaly cd into repo and git push --force. enjoy!
If you have a large ammount of contributions, you may want to use an alt account. (Make sure to set GIT_COMMITTER_EMAIL and edit commits.sh to pass --author to git.)
