Does anyone know of anything comparable for CS? I have a BA in another field, have been an entrepreneur since my mid-20s and am now a self-taught programmer. I generally don't contract or work full time for other people. But I would like to get a CS degree for personal growth. I can't really justify it being too disruptive so it would have to be:

1) Flexible. 2) Not terribly expensive.

Currently "questionable" accreditation would be ok since I think people's opinion of online schooling is likely to change dramatically over the next decade.

What I'm looking for is an extended CS-related challenge with some manner of official closure at the end. For my own personal satisfaction I would like to say I finished a second degree as opposed to saying I finished some free MIT courses online.

Anything worthwhile available out there?
