If you want MORE green why not chuck some extra 1/2 + Green or WFG.

You can get the flickering by having one of your electrics crew hold the male end of the plug half into the socket and when it doesn't quite make contact it will flicker.

A flickering effect on commercial flourescent fixtures can be achieved by using a variac dimmer. Start with the unit at line voltage and slowly begin dimming down until you find the "sweet spot" where it begins to flicker. Good luck!

for the shutter remember that over 1/60 you will have flickering so it must be on 144° or less.

I got a cool effect once by putting a Kino on a Magic Gadget, with very irregular flickering. It's touchy though, you have to find a "sweet spot" where the voltage is enough to get the ballast to kick, but not turn fully on or not strike at all. Not sure what that may be doing to the ballast, though...

Thanks for sharing your gig with me. I would like to get a visible flickering as a fixture with faulty ballast . I will try the magic gadget and try loose the male end of the fixture. does your kino+magic gadget gig gives you the flickering effect I am looking for? or it just trun out to be flashy kinda flickering? thanks.

I can't say for sure how your fluorsecent ballast would react. Some commercial ballasts might just crap out altogether, who knows. And of course using dimmers or flicker boxes means you have to have a fixture with an Edison plug on one end -- practical ceiling-mounted fluorescents are hardwired into the building.
