Being partially color blind, I can “stop the motion” of these pix by simply fixing my point of vision within the image.
i am colorblind as well and it may be why some of them don’t work for me that well.
I have MS and some optic nerve damage...none of them move for me. I also never could do those 3D books where you hold them close to your nose them move them away and you’re supposed to see a 3D image...I just looked like a fool trying over and over to move the book back and forth from my eyes, LOL.
Actually, it's the fact that your eyes move around the picture that creates the illusion of motion. They would also appear to move if they were in black and white. When you fix your vision in one spot, they stop moving.
