This was a not-so-impressive #tribute to this burger advert: https://vimeo.com/178939743 and here is a similar Smores advert: https://twitter.com/MachinePix/status/994279… But isn't is a shame we waste so much human effort and ingenuity on advertising (and silly dweets), instead of solving the world's problems? #capitalism #cognitivebias

It just loads forever :P
u/joeytwiddle

Oh I didn't realise it was suppose to finish loading!
u/magna

Yes, ideally, the loader should show progress when t is between 0 - 1. But I think infinitely loading progress indicators like these are totally fine as well!

Oooh I see, thanks. I thought we were just doing loading spinners for fun, but they are for https://dweet-player.herokuapp.com/

This has fewer start points and slower motion than other bubble universes, so we can see how the galaxies transition
