gitk - The git repository browser
Displays changes in a repository or a selected set of commits. This includes visualizing the commit graph, showing information related to each commit, and the files in the trees of each revision.

Within this pane you can see:
There are also two 'search' functions:
Explore through each view, there is some hidden functionality - right click and see what pops up.
I don't use this view much and I'm sure you could get similar functionality via the command line and using something like grep, but for a quick 'who did what' gitk is very useful.
