Hay Box

I've long been intrigued by the idea of a hay box for cooking, but haven't got around to building one.  Has anyone here any experience with it?  I would think something other than hay (like recycled styrofoam insulation, chipped, in a cloth bag) would work as well or better than hay, which is fine if you have lots of it on a farm, but a nuisance for most of us.  There's lots on the internet about it - I just wondered about different experiences here.
