Blacking out a glass pocket door?

[puntloos]

Other than the semi-obvious (curtains) - are there any good ways of blacking out a pocket door that has glass elements?

 

We like wood+glass better as a separator between kitchen and livingroom, but livingroom has a projector so needs to be as dark as possible, while we've designed our kitchen with as much light as possible. Any way around this?
