Video of a programmer using Emacs... for programming?

Question

I've started programming Erlang in Emacs. I keep hearing about how productive Emacs is, but every screencast I've found involves something silly, like (I'd post the links, but I don't have the rep.):

• creating an HTML table!
• emailing a project plan directly from the editor!
• browsing the web!

I'd like to see a video of programmer's workflow, using Emacs to actually work on a real project in a real programming language (Erlang, Lisp, Clojure,... anything!).

Answer 1

I've not found examples of complete project workflow as yet, but these may be somewhat closer to what you seek:

• RSense (Ruby)

• Emacs with Clojure, Slime and Swank

UPDATE:

• python!

Answer 2

Emacs Wiki has lots of screencast regarding programming :
