It may sound stupid, but try learning some card tricks or play solitaire with some playing cards?

I’d go along the lines of tildaverse but with a community area, like nextcloud, matrix and, lemmy. Nextcloud as a gdrive/O365 alternative for users. Matrix as an irc kind of thing. (May have the wrong application for this but an irc aspect too.) And Lemmy as a support/ideas sharing platform

2 dimensional time?
