Black holes, universe boundaries and geometry

A quick novice question. What sort of shape would project a holographic reality (Kind of like water spraying from the inside walls of a sphere) from the boundaries of the universe and at the same time contain drains (black holes) that feed the shower?

A 2-dimensional surface can for instance, project a 3-D image. If that is what you are asking?
