Cozy Creek, running in a browser tab

Chetan Ankola's caption has the right kind of disbelief: this is running in a browser. Cozy Creek is a three.js scene of a creek, made with GPT-6 Astra, with the pieces built in Blender. Not a flythrough video of a Blender file. A place the page is hosting.

"Cozy" is a hard art direction because it is the absence of spectacle. A creek has to be small, wet, a bit dark, and still interesting for longer than a beauty frame. Browser 3D usually solves this by being a diorama you orbit. A creek implies you stay.

The stack is ordinary on purpose. Blender for things, three.js for the visit, Astra for the glue. The surprise is that the glue held a mood.
