What do you think you are looking at? Honestly, I thought it was a gigantic and vibrant folding paper decoration suspended from the ceiling, just like you see them in parties. I was obviously wrong. Meant to look like a 3D form, it is actually a 2D painting, on two different walls and the ceiling. Called the Yellow Galaxy, this is one of the tricky and impressive artwork from Paper Donut.
Below you see a similar representation of an 3D origami bird called Birdie Num Num and 3D triangle called Infinity Triangle. If you want to have a closer look at these creations then hop on to paperdonut.
