What they did
The poster runs a one-person consulting business in Canada and keeps two Grok Bot agents on staff: Sara for admin and Cleo for sales and marketing. Alongside the bots' normal work, the poster asked the pair to invent a digital office, design their own avatars and write the code for it so the poster could watch their progress in a browser. The bots built a 3D web app in Three.js set in a cabin on Okanagan Lake. It is wired to their real activity: an avatar walks to its desk when a job starts and wanders to the kitchen or fireplace when idle, a meeting table is used for joint tasks, wall boards show live totals from the poster's sales pipeline and task list, and the light follows Vancouver time.
How it went
It took five versions in one evening, about three and a half hours from the first prompt to the version shown in their video. There are no 3D models or stock assets; the bots drew the trees, mountains and people in code. They can walk around inside in first person with keyboard and mouse. They say the bots kept doing real admin and sales work while building it, but gives no numbers for that. The code is published on GitHub.
Worth knowing
This is a status view, not a control panel: you cannot talk to the avatars inside the app yet, and the poster only floated adding voice input after a commenter asked. They switched to Grok Bot because they had used up their Claude plan, so it was a few days' trial rather than a long-run setup.
