Let's begin by stating a general problem, the limitations of the human mind. The human mind is trapped within the borders of the X,Y and Z, incapable of fully understanding such concepts as the meaning of infinite, or physical extension outside the 3 dimensional space (despite the fact that we are able to calculate them using the rules of mathematics).
The 'spacetime aviary' is an experiment to reveal an unknown perspective, inspired by quantum physics and other indistinct sections of nature, such as: Magnetic fields (super conductors), that are able to trick our mind's basic expectation about gravitation. Black-holes, regions of space in which space and time are distorted in such a way that nothing, not even light can escape. Holographic images, which are able to store information about an entire object. Even if the hologram is cut into pieces, each slice will contain fragments of the whole image. (Implicate order, David Bohm, ca. 1980) As well as experiments on separating certain sub-atomic particles, such as electrons (Alain Aspect, 1982), showed that the resulted electron pairs are able to instantly communicate with each other, regardless of their distance, as the correlation between their wave functions remained. This is in one way questioning Einstein's theory about that nothing can travel faster than the speed of light. In other hands, it is a good example to highlight the possible existence of other imperceptible dimensions. If we think about the tangible space as a small fragment of the universe, only as a projection of something that is behind, everything within this world becomes a fake illusion. The spacetime aviary is an experiment to hack the universal rules of nature, to create a new dimension.
Imagine it as a sort-of black hole. There is no gravity, and no such factor as time. The wings swing in an endless loop, though nothing can escape from this space. The 'bird' itself symbolizes nature, but it is presented in a rather mechanical shape. After all it is only the illusion of an un-known dimension.
