[glorp's Lab]
A compact, cluttered workspace.
A benchmark cow is near the north wall.

> say hello
You say, "hello."
A glimpse of the lab. The cow is really there.

A few doors to try.

  1. See who's here

    A list of connected players, plus people's homepages.

  2. Read something

    Books written here, and public mailing lists for the longer conversations.

  3. Look under the hood

    Browse objects and public MOO code. There's command help and a project task list (login required).

  4. Keep up with people elsewhere

    Use @fedi to follow and read ActivityPub and Bluesky feeds from inside Mongoose.

What's new

  1. Fourteen text-playable table games at The Arcadeum

    2026-10-18

    The Arcadeum has fourteen new table games, from Pig and Shut the Box to Hex, Quarto, Nine Men's Morris, Skull and Love Letter. Read help games for the full list and seat counts, or browse a title at the tables.

  2. @dig works in rooms you own

    2026-10-18

    @dig now works only in a room you own. In anyone else's room it tells you so and changes nothing, whether you're making a new exit or changing an existing one. To connect your building to someone else's room, ask its owner.

  3. Checkpoints and undo for your building: @wsv

    2026-10-18

    Builders can now save a checkpoint of what they're building, see what has changed since, and put changes back. Put the things you own into a workspace first:
