The speed of this GIF is incredible: it whooshes left to right, without any metronome-like regularity. So it’s kind of like listening to someone play piano in 4/4 rhythm, but who breaks with that regularity every several notes. Just because they can, and because they know how. Originally this GIF was part of the Wrong Biennial. Though the GIFs on that site have been removed, you can still see Yoshi Sodeoka’s Plan 9 Channel 12 Pavilion here.
