Also - please check out the video below, just to give you an idea of the effect of the "sunshine bird"...
One of the Mutual Musings projects.
A poem-in-a-box.
There are 3 bird shapes cut from the poem-backing card which also reside within the mini-tower-prison. A fourth shape has also been cut into the roof/top; under the right lighting this can cause a "sunshine bird" to illuminate the prison walls.
The poem rolls up to be sent inside the prison-box, and then symbolically freed by the recipient.
