I wish the pieces had descriptions explaining the connection between the math and the visual in more detail. Particularly, I was looking at this one: https://imaginary.org/hands-on/the-harmonic-series-2-3d-scul...

As an amateur musician, I find the idea of 3d-printing chords a fascinating concept, but the print here looks like it's formed into a cube shape and it's not at all clear to me how one gets to a cube from what I assume are three sinusoidal waves (one for each note in the triad).
