Floating Portals

From the Introduction: A star filled void surrounds this ever moving arrangement of portals and platforms. Slowly the two walkways leading to the portals, one emitting a red the other a yellow glow, and the central platform to which they are chained revolve around a central pylon glowing with a soft orange light. The way from one portal to the other is nothing for those afraid of heights, as you have to balance across the chains connecting the stone platforms on your way, with no ground in sight anywhere below you while you still firmly feel gravities downward pull.
