i looked into birdhuts/birdnests/birdcages. Artists that i have used to show inspiration and possibilities for further ideas are Joost Bakker and an installation in Sydney Lane called 'songs of forgotton birds'.They both consist of a series of hanging birdcages to create a floating effect, i take from this both freedom and restriction;

- restriction represented by the cage itself.

-freedom represented by how the cages are displayed, as if they are floating.
