A tiny script to display the entire contents of a medium sized git repository. It will display tags, branches and commits with different shapes and colours and the commits messages in a dimmed colour.
It relies on graphviz to do the plotting. Use it like so
ruby plotrepo.rb /path/to/repository | dot -Tpng | display -antialias

This is useful to show the entire repo with all the branches and everything especially when training students on how various operations alter the repo. I find it much more understandable than that of gitk.
This doesn't work for huge repositories.
