..maybe it's "dirty" but one may achieve the same with using global variables
(var in the example).

BTW, the vtkInteractorStyleTrackballCamera has a weird behaviour in rotating
the scene.

from __future__ import print_function
import vtk

var = 0

class vtkTimerCallback():
   def __init__(self):
       self.timer_count = 0
   def execute(self,obj,event):
       global var
       print(self.timer_count, var)
       self.actor.SetPosition(self.timer_count, self.timer_count,0);
       iren = obj
       self.timer_count += 1
       var += 1 
def main():

if __name__ == '__main__':
