"The term orb describes unexpected, typically circular artifacts that occur in flash photography — sometimes with trails indicating motion — especially common with modern compact and ultra-compact digital cameras. Orbs are also sometimes called backscatter, orb backscatter, or near-camera reflection." http://en.wikipedia.org/wiki/Orb_(optics) I myself have seen orbs that move, in my web camera in my son's room. It was an amazing experience. *CSS by Baby Jane
