A turn-based queue lets different visitors operate the same machine. It turns using a computer into a peculiar spectator sport.

The next person gets to pick up where someone else left off. Shared control makes even an ordinary desktop an unpredictable social experiment.

These are public, shared machines: never sign into personal accounts or enter private information. The site also warns that other users may display NSFW content despite moderation, so this is not a work-safe recommendation.
