+1 on the Gulfman dual illuminator. Looks very cool.
I also love the rescue orange Riseman's backlight. Standard greenish tint, which looks cool next to the orange case. But when the light's on, you see a kind of holographic rescue tool. Orange, looks like an ice axe.
Sorry I have no good pic's. Haven't mastered the art of shooting in the dark.
I understand some of the surfing G's have a surfer in the backlight, but haven't seen it yet.
