On my side though, I hyperfixate on the surfaces of quite a few mundane things in rotation, namely: Wikipedia-surfing, peripheries of federated protocols (more Matrix, less AP), manga titles, maps and transit, money tricks, some oddly specific Roblox games, keyboard covers of pop songs, etc. just to kill time when, way too often, I don't (think I) have the energy to actually do work beyond what's strictly required in the short term, and I don't have other options (like going out)...
