Moving stuff can get very complex and I'm not always convinced more is better. A lot of weird stuff happens in our brains with regard to movement perception. Loads of examples highlighting the weirdness but eg in the animated image below dark background (+ grid) is rotating with three stationary yellow dots and a blinking green dot in the middle. Look at the green dot and ... the yellow dots disappear, sometimes all, sometimes just one ... and then reappear but they are not -yellow dots are solid no flashing. It's your brain processing movement and deciding to ignore stuff. (On some screens it doesn't work apparently to do with screen technology and pixel refresh details).

note: on my phone the background isn't rotating so doesn't word but on my tablet it is and does work (both in Safari browser) -Reason for this: I have this website set to not play animations as a few people have highly irritating animated avatars.
If you cover the green dot with something so that you can't see it, the yellow ones still disappear.
