Built using the Copilot SDK, each window is an iframe backed by a separate Copilot session. The UI is rendered as plain HTML, and user interactions (clicks) are sent back to the model as element IDs, which responds with HTML diffs to update the UI. The result is a fully interactive fake OS — complete with calculator, browser, Paint, and nested simulators — that produces plausible but entirely hallucinated content. The project took Steve roughly five to six hours and is presented as a live demo at a developer conference hosted by Scott Hanselman and Mark Russinovich. ## Full article daily.dev links to this article rather than hosting it.
