Successful art, like all psychoactives, creates a parallax effect for the audience. The artist crafts a sort of "reflector" -- i.e., a proxy perspective through which the viewer can experience reality "from elsewhere." This new perspective illumines the world's internal relationships as only movement can; as the viewer assumes a new position, stars in the foreground shift relative to those in the background.
This new perspective is not just additive -- it is exponential. To occupy it, the viewer must move telepathically along axes known and unknown; previously impossible qualities of the self are revealed, forcefully recasting the world. This is a form of hyperdimensionalization.
