Monochro is a home design studio from Japan, founded by Momoko Naito and Atsushi Fujii, who graduated from Tokyo Zokei University. One of their works is this light blue butterfly wall ornament.
The design is modeled after the large Morpho butterfly that lives in the Amazon basin. It can be attached to the wall using thumbtacks and magnets. The angle of the butterfly's wings can be adjusted freely to create a more vivid and lifelike scene.
(It is even more interesting when paired with the leaves in the wall stickers here.)
