It is difficult to categorize the kinds of videos that Posy makes — they are part science demo and part visual art. His latest video, Household Objects (But Extremely Close), uses a powerful macro lens to look at everyday objects like toothbrushes, sponges, and pencils, turning them into swirling abstract films. His music is lovely too — you can find it on Bandcamp.

In this video from his YouTube channel “about anything”, Posy demonstrates a video filtering technique called motion extraction. A commenter calls this video “a tutorial, a demonstration, and a work of art”, all rolled into one. It’s really lovely and informative. My jaw actually dropped at the “how can you tell which stones were disturbed on the path” part.
