@randynose this is pretty rad. how are they getting the different movements?

different rates of spin?

@randynose I think with the directional movement they're just moving the arrows. but IDK about the shrinking / growing ones.

@levi @randynose I cover them with my hand and they still move so maybe that's not it

@randynose This is fake.
I extracted every frame.
Everything was changed frame-by-frame.
The moving around, growing/shrinking, everything.
Don't believe me?

ffmpeg -i path/to/media.file frames/%03d.jpg

Inspect the frames yourself located in the frames/ directory.

Well, if I put the mouse pointer on the edge of the Circle, it doesn't appear to move from the pointer.
🤷‍♂️

@randynose I've reviewed the frames probably 6 times now. Either this is a very good illusion that it's fooled me 7 times, or it's fake.

Not trying to be confrontational here, I just realized how it sounds.

I'm just really skeptical about this.

@Phate6660 @randynose but if you just look at the edge of a circle it doesn't move?

if you just compare two frames, wouldn't the optical illusion still make it look different?

@Phate6660
@levi
If one had grids setup on the Gimp and overlaid the frames, you could inspect each frame, and also use opacity to check out the gif.

@randynose Is it the colors on the thin edge that make it?

@randynose If you repeatedly blink you will be able to see circles aren't actually moving. It's very weird...

@person Kind of makes sense, if you're blinking at the same rate that the images are being processed / displayed.
