The following link (from transferbigfiles) gets you a nearly 1gb sized video that plays for 23min and explaining
some much needed concepts of the anatomy of lisp. Note that depending on your connection the file may take from 10min to much longer to download.

Let me know if you find it useful, and I might continue a few more.
ps: If you want to see how it sort of looks like, you can check it out on google video.
Note however that you will have hard time reading most of the writing since google video
compresses to quite a low resolution (which is why I had to put the original on transferbigfiles)
