I know it's mean to tease you with a topic of a new prop without photos, but I am in the process of spray-painting it right now.
At the flea market this past weekend, I picked up a pair of novelty handcuffs based on the movie franchise "Police Academy." These are a pair of plastic police officer hands, with thumbs that open and lock into place, connected by a chain. I am spray-painting the entire thing green (sleeve cuffs will be kelly green; hands are going to be fluorescent green).
When I am done, I should have a cool "construct" prop resembling a Ring-Generated pair of disembodied hands -- perfect GL props (IMHO). I plan to use these as a dedicated prop for G'Nort unless they are needed for something/one else. I think they will pay for themselves at the Dragon*Con Lantern Shoot, as I cannot imagine ANY Green Lantern costumer will not want to be photographed standing next to, say, Sinestro, in a pair of these. If a non-Lantern Bad Guy wanted to walk with the League of Lanterns in the Dragon*Con Parade, they could wear these and be "en route to a sciencell."
Problem - the cuffs did not come with a key. A simple toy, I am confident that I will be able to pick them, but then I will need to fabricate a handy skeleton key for them.
Photos to be posted soon -- I promise...
