Love it. A small piece of feedback: On mobile, the page jumps after the electron cloud PNG loads. This causes the dreaded 'tapping something I didn't mean to tap' effect. Could you set the height of the space before the image loads to prevent the jumping, or something similar?
Cool. Reminds me of ptable.com , a little.
Ptable renders them with WebGL from the quantum numbers using the Schrodinger equation, wrapping a threshold density of the generated point cloud with a surface.
