We're changing that joystick to a VCR like play button.

The commit one being a box hints at a shell or terminal, since we couldn't find an official Git icon. Could maybe put the GitHub Octocat there - what do you think?

How about the icon from the Git website?

Octocat gets my vote.

You would have to ask Github, as they own the copyright to Octocat.
