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 wasn't that impressed until he used the ruler. My mind is so broken! Another interesting thing about illusions involving rooms and windows is that apparently they don't work on primitive people.... and... OK, he mentioned that in the video too at the end. Top notch. Thank you for linking that.
