Illusion of the Year 2019 Winner

the site is getting hugged to death unfortunately so here the relevant content:

> 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.

I'm really not seeing fluid motion in any direction. I'm seeing a fish explode to disassembly and reassemble pointing the other way.

I see the rotation when there's the great big opaque cylinder in the middle of it, but it doesn't last after the cylinder is removed -- it reverts to explody fish.

This one is also interesting!
