This 2020 short film was presented by Dust in 2022.

The film has no dialogue. There's just a hovering robotic... sort of mini-vending machine, I guess. Someone buys a soda from it, and doesn't take their change. The robot then flies down into like a sewer or something, where a starving man takes the change to use in a regular-sized, stationary vending machine that offers all kinds of services, including finding a lost child. The man scans a picture of a pig, claiming it's a lost child, hoping that the floating robot will bring him something to eat. And it just gets weirder from there. It's... I don't even really know what to say. It's just really interesting in its bizarreness.
