Probably just a demo to show off their capabilities.

What will they think of next?

To think something like that in your mind is one thing. But to actually build it is really cool.

Gears can take many shapes https://imgur.com/gallery/tig3sGP utterly useless as a gear train but cool...

Wow, that's pretty cool. But, there's still the issue of balance that has to be reckoned with, especially in high speed motion.

I think it's more of a demonstration that gears don't actually need to look like gears, than an actual geartrain design. It would work well for an art automata or something like that.

or for a steaming pile of punkrock watch parts to be mounted on the clock tower for another lightning strike in 2055 100 years after the first one and send us all back to when it was safe to poke your eye out with a loose untied shoe lace...and drink koolaid...and elections werent so fraudulent with zero way to confirm "mail in votes" I sure hope that they get that thingy connected to the flux capacitor soon!!! run Marty run!!!!!

or for a dough mixing machine.

how about a really big one, and call it an anchor?

or possiably it's for one of those sock knitting thingys...or braiding machine......IT A PRETZEL MAKER!!!

Many years ago, the Royal Aircraft Establishment at Farnborough in England, set up a project for stuff like this for the apprentices, probably to stretch their imagination, after all Farnborough was(is) an experimental facility. One submission was a model bicycle with triangular wheels. True,it needed a special "road" (much like a rack), but it did work.
Aside from satisfying the project parameters, it was about as useful as tits on a bullfrog.

just think about a wankel/mazda rotery engine....wtf? that cant work!!! and yet it works just fine..and can be expanded upon. just because something looks wonkey dont mean it's a donkey.
