Nothing, just an animation.
I found this music term on Wikipedia, so I decided to make a meme about it. I am learning music theory, but I have never seen this term, the closest I've heard is a demisemihemiquaver, which is a 64th note. The note shown in the project, a demisemihemidemisemihemidemisemiquaver, is a 256th note. Short, right?
