A brain in a vat is a thought experiment related to consciousness and the perception of reality which has, in one form or another, interested people ranging from philosophers, to philosophically-inclined science-fiction writers, to B-movie horror authors. This piece of origami treats the subject literally.
Designed and folded by me. I learned folding the pattern which became the basis for the brain itself from Joanna Sobczyk who uses it in some of her fractal flower designs (here’s an example). While this particular work is just a single brain in a box, the brain itself can with a slight modification be tessellated and I hope to fold a piece with multiple molecules some time.
This model is folded from a hexagon of Tant (8×8×8 grid). It should be relatively easy to make a variant incorporating color change but one would probably have to use a larger, less convenient to fold grid.
