I think somebody once posted a link to Penn State that may have had some free courses, too, but heck if I can figure out how to search for it 
Forgot to add - the tamu.edu page has lots of classes that are free to take, but you'd have to pay for a certificate if you wanted it for some reason. The cost for the certificates is still reasonable though.
There are quite a few of these that are completely free--even the certificate.
