There seems to be a whole bunch of these kind of films, though none appear quite as creative as the above one looks. If you're into this kind of stuff, here are a few more examples.
The full Psychomania in 4 parts
Werewolves on wheels (full)
Satan's Sadists (trailer, should be enough for most people). - You can stream this whole film through Netlflix, which I'm not ashamed to admit that I did. But it made me feel kind of sick and I stopped it half way through, which I am kind of ashamed to admit that I did.
