Oh no! You are falling down towards a self-similar quasicrystal!
Luckily you are shrinking as you fall, fast enough so you'll never hit bottom. You can see how this was made on the blog We Alone On Earth
They point out that this is similar to a Shepard tone
, a bunch of parallel rising tones that give the impression of a note that endlessly gets higher in pitch: as some tones rise too high to hear, others from below take their place.
They say that after staring at this long enough, when you look away everything will look like it's shrinking!
I haven't gotten that effect yet, and I'm not sure I want to.
