Experimenting with GIPHY, and gif as a medium.
Pros: plays nice with almost any platform (incl. this one), infinite loops, low filesize.
Cons: Low res, small embed, no 360 degree equirectangular VR fun, no(?) audio.
Conclusion: for fun experiments, throwaways, smaller stuff, WIP. Not for ‘serious’ work / final versions.
(I think I knew that already.)
