In these pictures in lower right corner can be seen a sphere that is changing its shape.
I wonder how I can build this sphere. Probably it is some kind of sin function or something similar. The direct link for demo is here.

Maybe some function with Perlin noise would work or I though I could use some function with sin and some random values like A*sin(a) + A*cos(a) + A*sin(b) where A is some function of random values and interpolated and a and b are angles in spherical coordinates. Would something like this work ?

x += amplitude * sin(x * k + time * omega)Do this for each coordinate separately, using different wavenumbers (k) and frequencies (omega).
