Git tree with selectable nodes in terminal?

Question

Emacs has an optional undo-tree. You can cursor to each node, and hit return to go back in time, even along branches.

Is there something similar for git, which can be accessed within the Terminal (not Emacs). So, within a git project, I could type a command and it would show the tree. I could cursor around, going back in time or even switching to another branch, then hit return and it would checkout that particular commit's whole state.

As @NevikRehnel said, tig is your friend.

tig --all shows you your complete log in a tree form (as git log's --graph switch).

You move between commits with up and down keys, you see a git show of the selected commit with Enter, and you can hit Shift + C for doing git cherry-pick of that commit.

You can press H anytime to see help.

You can checkout branches, but you can too add custom bindings for doing git checkout.

I think man tigrc would be enough to understand how.
