Does anybody know the code to plot the following picture: enter image description here

Having trouble to come up with a good idea...

I'll leave the mesh lines and the coloring up to somebody else:

With[{c = 3, a = 1, n = 9, r = 1/3}, 
     ParametricPlot3D[{{c Cos[u], c Sin[u], 0},
                       {(c + a Cos[n u]) Cos[u], (c + a Cos[n u]) Sin[u], a Sin[n u]}},
                      {u, 0, 2 π}, ColorFunction -> (Hue[#4/(2 π)] &), 
                      ColorFunctionScaling -> False, Method -> {"TubePoints" -> 30}, 
                      PlotRange -> All] /. Line[pts_, rest___] :> Tube[pts, r, rest]]
