42 seconds · Silent. One PC, then two. Eclipse on Windows, recorded full screen: it streams one PC’s desktop, returns to the library, then opens co-op, picks a layout and starts a two-PC session. Eclipse offers to close the app still running on the first PC before co-op begins. Each half of the finished screen is a different PC, showing its own desktop.Recorded by an AI assistant (Claude) while the developer was away, as a capability test: every click and key press was planned in advance and played back automatically on live hosts.
