There's an interesting symmetry between the image and sound frequencies "kiki" has lots of high frequencies: the i and the click sound of the k. Sharp corners

There's an interesting symmetry between the image and sound frequencies "kiki" has lots of high frequencies: the i and the click sound of the k. Sharp corners also have lots of high "frequencies", but in the 2d domain. There's an equivalent symmetry, except with low frequencies, with "bouba" and the rounded shape. I feel like this can't be a coincidence
