Step through a file's history in git; similar to p4v timelapse

gitk -- filename should do what you want, if you kick up the lines of context in the middle, and scroll up and down through the revisions.

Tig, a text mode interface for git, offers a blame view that offers some of this functionality:

• Step backwards in time to the commit of a given line (b key).
• Step backwards to the parent commit of a given line (, key).
• Returning forwards in time to a view you were at previously (< key).

It does not preserve the viewing location when stepping to a parent commit (it seems to when using the line's commit).

Here is a Git Time-Lapse View tool that I have written in Java:
