I did this small Class to solve my animation needs
http://paste.pocoo.org/show/190229/
maybe it helps.
usage is really simple.
def complete_tween(message=''):
print message
@win.event
def on_mouse_press(x, y, button, modifiers):
Tween(my_sprite_1, 1., delay=0.5, vars={'x':200, 'y':300,
'opacity':200, 'rotation':90})
Tween(my_sprite_2, 1.5, on_complete=complete_tween,
on_complete_param={'message':'on wrapped_sprite'}, vars={'x':200})
you can tween any numeric property of any object.
you can add a callBack function when the tween reach its end.
