Whose Famed Weapon Is Tony Stark Building In Iron Man 2?

This may be soundless, low-quality leaked footage of Iron Man 2, but that's certainly Tony Stark holding one of the most iconic pieces of superhero paraphernalia in comic book history. Spoilers way on!

It's a prototype for Captain America's shield, natch! We saw this in Iron Man, but here Tony actually gets his paws on it.

We're in the waning moments of Iron Man 2 spoilers, so we'll have this mystery Easter Egg solved in six days. Who knows what's going on without the sound? Maybe Tony's just building the Frisbee of the future.
