Wired got a glimpse of how German VFX company Pixomondo created Daenerys' three dragons, and the terrifying amount of work that went into it. Researching how big the wings needed to be, figuring out flight patterns, waving tennis balls on sticks at the actors — all this and more was required to bring Drogon, Rhaegal, and Viserion to life.

Is anyone else morbidly looking forward to the inevitable Red Wedding VFX featurette, or is it just me?
