Tamai
The grid where stuff Just Works (TM) (except when it doesn't 😁)
Tamai is a virtual world that is part of the greater hypergrid metaverse.
You can teleport to hg.tamai.nl:80 from any existing hypergrid-enabled grid such as OsGrid.
Unlike most other grids, I do develop inhouse and don't use vanilla OpenSimulator binaries. I also share my code back. Here you can see the features implemented so far. It may not seem much, but it drastically improves the inworld experience and hypergridding.
Tamai is a private grid that is open to creative-minded people. Making an avatar is possible now. Parcels available at a later date, use the sandbox in the meantime.
