My OnDraw() looks something like this:
            glMatrixMode(GL_PROJECTION)
            glLoadIdentity()
            gluPerspective(20, 1, 20.0, 1.0)           # why 20 > 1 ?
            gluLookAt(x , y, z, 0, 0, 0, 0, 0, 1)

            glMatrixMode(GL_MODELVIEW)
            glEnable(GL_DEPTH_TEST)
            glEnable(GL_LIGHTING)
            glEnable(GL_LIGHT0)
            # Draw cube
            glLoadIdentity()
            glBegin(GL_QUADS)
            ....
            glEnd()
            self.SwapBuffers()



If anyone has any good ideas on why my gluPerspective works funnily then 
let me know!
for example, does it make a difference in which order Perspective and 
LookAt are called ?
