When it flashes a small black/white line is positioned on a specific borders to give a feeling of movement.

If you want to understand better how -- pause it when the cubes are rotating. The white/black edge lines actually have to gradient across the line so that one half of the cube moves one way and the other half moves the other. You can work out which way 'turns' what and how they're placed. I'm sure a cube was the easiest, but you should theoretically be able to do this with any shape.

What the hell are you guys talking about? Flashes and rotating?

Maybe it's not working for you, but it works on my phone... The lines of which the cubes are drawn are white/black. By changing the amount of each on a side, (WHITEblack whiteBLACK BlackwhiTE blackWHITE etc) in quick succession, one edge of the cube can look like it's approaching or receding. It's based on the way shadows would behave for a real cube, and your brain processes it as such. (The ones I made up aren't in any order, whereas the ones in the gif are carefully synchronized)

No difference on my phone vs desktop.

Sounds like a skill issue.

[–] bitchkat@lemmy.world 1 points 4 months ago (1 children)

opening a jpeg sure requires a lot of skill.

It's a good thing that it's not a jpeg then. So looks like you're opening a JPEG of a GIFV/MP4 file.

Dunno how you're managing that - but...skill issue. Because everyone else seems to be seeing the GIFV/MP4.

Oh that's interesting. I'm browsing lemmy.world on my desktop. I click on the thumbnail and get :

Yes thank you. I covered up the arrows and it still looked like they were moving.
