What people are building with GPT-6 Astra.

A macOS simulator written in 75 minutes. An old drawing of a steam train rebuilt in Blender as 3,295 editable objects. A game that took one prompt. We are collecting the best of it here, each in the builder's own words. Nobody in these bylines is on eChai, and every post links back to where it was written.
