The Best Illusion of 2019 title in the Best Illusion of the Year contest goes to this Dual Axis Illusion mind-bender by Texas-based developer Frank Force, who writes:
This spinning shape appears to defy logic by rotating around both the horizontal and vertical axis at the same time! To make things even more confusing, the direction of rotation is also ambiguous. Some visual cues in the video will help viewers change their perception.
You can play with those visual cues thanks to Force’s this Dual Axis Rotation Illusion interactive on GitHub.
