operating systems should have a global bpm counter, controlled by the currently playing media, that apps should use to time their animations to.
@amara I miss BeOS.
(No, it didn’t have this feature AFAIK, but it feels a very BeOS thing to do.)
@amara In Mario games, the various critters do little dance moves in time to the music and it's delightful. Bringing that to an operating system would be great.
