We present the "Cartoon Animation Filter", a simple filter that takes
an arbitrary input motion signal and modulates it in such a way that
the output motion is more "alive" or "animated". The filter adds a
smoothed, inverted, and (sometimes) time shifted version of the sec-
ond derivative (the acceleration) of the signal back into the original
signal. Almost all parameters of the filter are automated. The user
only needs to set the desired strength of the filter. The beauty of the
animation filter lies in its simplicity and generality. We apply the
filter to motions ranging from hand drawn trajectories, to simple an-
