Overshooting circuit ?

Hello Group,

i have a simple question, but did not find an adequate solution for
it, so i will ask the Gurus here ;-)

I know that Opamp designers do hell of a lot of work to make their
devices as perfect as possible (low noise, fast etc.), and most modern
Opamps do have internal circuitry to prevent overshooting.
But i want a circuit that does exactly this. For example, when the input
signal raises quickly ,say from 0 to 5 Volts (maybe a gate signal),
i want the output voltage to go from the initially 0 V to 8V, then 3 V,
then 7 V, then 4 V, then 6 V, then finally the 5 V. I do not know if my
description is clear; i do want a damped oscillation, preferrably with
VC damping.

My intention is to put a square wave from an LFO in the input, and
hook the output to a VCO, so i expect to get sort of a 
"Sproioioinnng..." sound.

Can anybody point me in the right direction ?
