I folded a model of the inside of an obsidian cave that has no exits.
Folded from "chaos black" origamido paper.
Photographed (with flash set to off) after the model passed the event horizon of a black hole.
I wish I would've read this earlier, because now I have an idea for a group of models. They wouldn't be done by the end of the month, though, otherwise I'd likely submit the set (the Guardians of the Beams from the Dark Tower series)
The Face, Faceplate and Helmet could all be folded from 1 sheet (very long rectangle) but would have to be refolded to change from the Faceplate to the face view. You would not need a base to stabilize the Face. The glasses would still need to be a separate fold.
This "Flip-Up" version consists of the fold consists of the following parts:
Face (White) - I rectangle
FacePlate (Black) - 1 Square
Helmut (Black) - 1 Square
Base to stabilize the Face when the Face Plate is flipped up (Black) - 1 square
Glasses - 1 very long-thin rectangle
