Ooh ooh cool idea! Thanks for all the suggestions - I think I'll try
the willow. IIRC it will grow won't it? If not I can always 'clothe'
it as suggested.

Andy, a primary school near me has made a willow tunnel in the
playground. It is in its second year and is pretty well green all
over. They have bark inside as "carpet". You can trim it with shears
if it gets too much top growth.
Let us know how it goes.
