Here is one circuit example: 
http://www.epanorama.net/circuits/strobo_12v.html

In the highest setting it could just do 2 flashes per second 
at highest power setting that was as brigt as one flash 
made by the flash unit of those disposable cameras. 
Actually the circuit uses parts from such camera 
(flash tube, main capacitor and trigger transformer).

This circuit is triggered from some external triggering source 
(so you send pulses to trigger input at the rate you want this 
to flash).
