I’d rather the pictures be side by side so that I can transpose them myself to get the 3D effect.
It’s hard to see the flickering as anything but flickering.
Wave your hand back and forth in front of your eyes at the same rate as the pictures are changing. If you do it just right, the image will stabilize and you will see the 3D effect.
If you squint just right it kind of pops in pretty good.
