stypi like feature

[Andrea Crotti]

I just encountered stypi http://www.stypi.com/

and I really like the idea of replaying my edits and all these kind of 
fancy things.
But of course I would like to do it with Emacs, is there anything 
already available?

If not with the edits, at least play like a movie the different commits 
in a repository
would be very cool :)
