Hey! This thing is still a Work in Progress.
Files, instructions, and other stuff might change!

Description
Sphere with additional radial deformation of SphericalHarmonics.
out.stl: l=15,m=2
out.stl: l=15,m=2
Instructions
more to come, I am writing on a c++ program to create those shapes..
You can download the program for windows here: github.com/bkubicek/sphericalator/downloads
Otherwise compile yourself using qt>4.7
Spherical Harmonics are also the solution for Schrödinger's Equation in the non-radial part. So you can geek out and imagine its either nuclear cores that are vibrating, or a strange "visualization" of exited hydrogen atom.
see e.g. en.wikipedia.org/wiki/Spherical_harmonics
or mathworld.wolfram.com/SphericalHarmonic.html
I have not printed any yet, probably support would be required.

This is great! I wanted to do that myself. I will print some of them. I teach space flight dynamics and spherical harmonics are used for Earth gravity field models. Showing the students physical objects for small degree and order would help them understand a few things.
