Slop buckets, when stripped of their smelly context, can make for some visually interesting art.

This anonymous Tumblr, shared on Reddit, hosts a collection of photos apparently taken from the slop bucket (restaurant jargon for “liquid trash receptacle”) of a of a Park Slope restaurant. New photos are uploaded daily.

The results function sort of like On Kawara’s date paintings, documenting the present moment. They’re also fascinating in a way that anyone who examines the tissue after blowing their nose will understand.
