​This is a nice example.

​I'm having trouble running the sample, since "glut.glutInit()" fails:
Traceback (most recent call last):
  File "C:\Users\Ian Mallett\Desktop\glut-cube.py", line 127, in <module>
    glut.glutInit()
  File "C:\dev\Python33\lib\site-packages\OpenGL\GLUT\special.py", line
326, in glutInit
    _base_glutInit( ctypes.byref(count), holder )
TypeError: 'NoneType' object is not callable
Mike, it was Python 3.3.0, PyOpenGL 3.1.0b2.

However, the code looks fine otherwise to me. Perhaps, can you clarify what
"the display is totally screwed" means?
