An Arrow That Can't Point Left Puzzles the Internet

from the no,-your-other-left dept.

This arrow looks like it is pointing right but it's actually pointing left. This illusion relies on a clever combination of reflection, perspective, and viewing angle. The illusion arrow was invented by mathematician Kokichi Sugihara of Meiji University in Japan. Understandably, people vented their rage on social media.

    I think he released blueprints for his previous illusions for 3D printing (which is how he creates them himself nowadays), so perhaps you can get your hands on those? Sign me up for one!
