The original mod is itself a 1.19.2(+) port of Literal Sky Block originally found at https://github.com/nanite/Literal-Sky-Block. Some code from the fabric port also used, which can be found at https://github.com/Gaming32/literal-sky-block-fabric/. Both of these projects are licensed under LGPL-3.0.
A simple wooden house with a glass ceiling revealing a sky - or a false sky made of Blocks of Sky! A door leading to the void can also be seen on the wall.
Similar to the previous underground house image, but this time some of the Blocks of Sky have been disabled with a redstone torch. The Blocks of Void have had similar treatment.
