I don't think this is a really good thing....any cheap flash that's able to meter through your own camera will figure out the right exposure much better than anything that's not connected to your camera. Perhaps the one big advantage of this thing is the high rate of flashes, which would require a pretty expensive flash :P Although a lot have a strobe option anyway. But anyway, just image that the flash light will only highlight your subject, which will freeze him/her in time. (normally the flash's limited to 1/250), but at least you can turn the power down to prevent the rest of your photo to get overexposed by all the light. Now, if you'd turn (like when someone would ride a bike and pass you quickly, and you'd turn around with it), you'd have a photo with a bend horizon...like a bit of a U shape....the background will be all blurred lines while (if the flash is quick enough) the subject will be incredibly sharp. Would be a nice effect =)
