The story yesterday on Digg showed the bright object, plus it's not that hard to find since it's the only thing that's not rover or not red. I forget the source of that Digg linked to, but it speculated that most likely the bright shiny silver object was something from the sky crane or shielding from the entry stage. Considering the violence with which Curiosity entered martian 'airspace' it would seem very unlikely not to find some debris.
