Apartment Birds: an AI that identifies birds by their song and paints them on the wall

A tiny corner of the internet doing one gentle thing well: a live, ever-shifting collage of the birds outside someone's apartment window. But the backstory is the real delight — it's a DIY AI build, not just a web toy.

As Ole Lehmann explains, the system listens through a cheap USB mic on the balcony, figures out which bird species are calling, and paints them onto the wall — with bird.onethreenine.net streaming the result as a live collage. No product, no pitch — just a calm, human-scale use of AI.
