A marmite resource which teachers either love or hate. Personally, I love it. Marmite me up all day long, if you will. It provides a never-ending source of educational videos, inspiration, challenge, provocation and kittens launching themselves at erratic torch-beams wielded by sadistic owners waiting for their cat to splat into a wall and bag them £500 from "You've Been Framed". What's not to like?
