Take Magicka.. an awesome little top down action wizard game that has four player co-op. www.magickagame.com/
My step daughter got a new bathrobe and she the first thing she did was run into me with it on and shouted "Look I'm from Magicka" the next thing was a that she wanted a Magicka style photo.
So.. we went to the loft.. aka geek command center.. aka small studio and set up some lights and stuff.
I used two softbox's one left and one right of her (up higher pointing down).. I also got a speed light with a blue gel on it under the right soft box pointing up to her (this would be the magic shes casting glowing.)
