What installation do you want to build?

There are a lot of fantastic installation like 'The Gates'or the light instalations. 'The Gates'is a instalation that is from Christo and Jeanne Claude

I would make a plastic bottle installation.I would make a playground with plastic bottles from volenteers who gather bottles.(washed plastic bottles) I would make a jungle gym which is shaped like a plastic bottle.

What would you make?
