Show HN: VibeCheck – a shared groove inspired by One Million Checkboxes

I loved how One Million Checkboxes made a silly shared space feel energetic, so I tried the same idea with sound. VibeCheck is a tiny collaborative music toy: a four-bar loop is always running, and anyone who shows up can “claim” one bar (claims time out after ~20 seconds), swap the chord, flip the inversion, change the rhythm, and hear their tweak on the very next pass. Everyone else hears it too, so the loop keeps evolving as people jump in and out. There’s a lobby chat if you want to coordinate (or not!).
