Is there git blame gui similar to bzr qannotate?

As a former `bzr` user and novice to `git` I'm trying to find good GUI tool for `git blame` similar to `bzr qannotate`. The latter has 2 major views: - file content viewer with short annotate information (who, in which revision changed the line) + coloring of background based on committer id and age of the change. - file log viewer: when I click on the line in file content I can see the revision when that line was changed and all log information about it. Screenshot: I see XCode IDE has such something like that built-in, although it's inside editor window and therefore is not very handy. So far I've tried GitX 0.7.1, and GitHub for Mac - they both don't have "blame" at all. I've just checked SourceTree for Mac, and while it has blame support, but it's rather rudimental and shows me almost the same as command-line `git blame`, although I can double click the line to see corresponding revision and changes in another window. That's still is not as good as `bzr qannotate`. Are there another GUI tools I can use?
