This is such an incredibly inspiring concept, and not just because the library exists online and someone took the time to calculate and program something that feels so interesting to use. The actual concept of a library that contains infinite information in labyrinth of identical hexagonal rooms is so fun to imagine, if it were a physical place. What stops it from collapsing under its own gravity? Does it have layers or is it an eternal flat plane of connected rooms? How is it accessed? What lives there, and for how long has it lived there? Prime roleplay material right there.
