The following account was recorded in the agent's log during your transmission: An absolutely massive, perfect cube of what looks like plain drywall is somehow hovering inside a giant, naturally occurring cave filled with towering crystalline structures, with sunlight from outside casting through the crystals and onto the cube's surface in a kaleidoscope of colors. The air in here's damp and musty, and there's the faint smell of fresh drywall and paint, which is really weird. Umm... a low-resolution livestream of a 3D printing timelapse is projected onto one side of the cube, the sound echoing off the cave walls. It's really quiet and still in here.
