The idea
A warm room for pastimes that never existed.
This is a community for people who love a hobby far too much to require it to actually exist. There is no membership, no equipment, and no possible way to do any of it wrong.
Invent something on the way in — competitive napping, cloud juggling, underwater chess — then settle into a warm corner and practise it. The resident cat will decide whether it is going well.
One warm room, entirely fake hobbies, and nothing at all you need to be good at.
