Ambigram Zoetrope Coin: this whimsical spinning coin just arrived in my @thecuriositybox subscription, with an ambigram of heads/tails on both sides (for complete ambiguity?) and a fun twirling coin zoetrope animation as seen via video aliasing.

Ambigram Coin Escape Puzzle: I just received this physics brain teaser in my @thecuriositybox The puzzle is the classic coin escape puzzle, and the special coin features a heads/tails ambigram as a humorous touch. A flick of a finger sets the device in motion to release the coin. Note that one metal ball got pinned for a bit! ✏️ the physics: centripetal acceleration and rotational kinetic energy will raise the small steel balls away from the center allowing the coin to fall through.

Ambiguous Suits & Hearts: I first discovered and posted the work of mathematician Kokichi Sugihara’s amazing ambiguous object illusions in 2017. Here is one more really nice example of his original work that was sent to me by my good friend Tim Rowett.

Ambiguous Object Illusion Set: This kit comes with four objects (three shown here) invented by mathematician Kokichi Sugihara of Meiji University in Japan. Polygons appear as circles in a mirror and vice versa, and the famous “stubborn arrow” that will only point to the right (or, in a mirror, to the left). I like how the base is also an ambiguous pentagon/circle, which like all these objects, is a result of a clever combination of reflection, perspective, and viewing angle. Thanks to the Vsauce team for producing this kit!

Ambiguous Object Illusion: an incredible new design by Kokichi Sugihara of Meiji University in Japan, the inventor of this illusion and art form. A clever combination of reflection, perspective, and viewing angle produce this striking illusion. My vote for best gift from the G4G13 exchange this year.

Another illusion design by Kokichi Sugihara of Meiji University in Japan, the inventor of this illusion and art form. A mathematically calculated combination of perspective and the physics of reflection produce this striking illusion that works in many configurations.
