Quantum Cubes adds five tiers of blocks that each contain their own pocket dimension.
Place a cube, right click it with a Quantum Remote and you get teleported inside a hollow room, from 20x20x20 up to 128x128x128 depending on the tier. Click the floor with the remote to go back.
The room belongs to the block, not the location. Break it, take it anywhere, place it again and everything you built is still inside.
Requires NeoForge for Minecraft 26.1.
