python and 3D moebius script

Hola,

I enjoyed your video here!
I recently developed a 3D tool which leverages the vtk library:
https://github.com/marcomusy/vtkplotter

import numpy as np
from matplotlib.tri import Triangulation
from vtkplotter import Mesh

theta = np.linspace(0, 2*np.pi, 30)
w = np.linspace(-0.25, 0.25, 8)
w, theta = np.meshgrid(w, theta)
phi = 0.5 * theta
r = 1 + w * np.cos(phi) # radius in x-y plane

x = np.ravel(r * np.cos(theta))
y = np.ravel(r * np.sin(theta))
z = np.ravel(w * np.sin(phi))
tri = Triangulation(np.ravel(w), np.ravel(theta))
points, faces = np.c_[x,y,z], tri.triangles

mesh = Mesh((points, faces), c='orange')
mesh.computeNormals().phong().lineWidth(0.1).lighting('glossy')
mesh.show(axes=1)

I would like to ask for permission to include your moebius script into the set of vtkplotter examples.

Muchas gracias, un saludo
