Looking for ideas

I've got about 200 sf of 3"x6' bamboo floor boards left over and I'm brainstorming ideas for what to do. I am dream-sketching a treehouse for the boys and wonder how the bamboo would do outside. Anyone know? How bout as a rainscreen on a treehouse like this:


(That's the model for our treehouse at the moment - we're reaching for the stars...)

So will bamboo swell/contract enough left out in the elements to cause a problem on a rainscreen? I'd rip it lengthwise into 1" wide planks, then fasten to furring strips. Will it pop the screws?

Other ideas for the bamboo: a table top (maybe a coffee table?), shelves for the downstairs closets, a bench...
