Git GUI like Bzr Explorer but for Git?

What GUI's are there for GIT that are like Bazaar Explorer?

Preferably for Linux.

Would be great to include or link to screenshots in the ans开发者_如何转开发wers.

If you could do each app as one answer, they could be individually voted on.

Install bzr-git plugin for bzr and then simply use Bazaar Explorer to work with your git repositories.
