Secret Captain America Cameo in Iron Man

Cameos make the world go round. We already know that HULK had a cameo in Iron Man... even if it hasnt been discussed that much but on top of that Captain America.. or I should say Captain Americas shield also had a shot in the film. Alex from FirstShowing tells us;

I've seen the scene about 4 times now, each time with a different group of comic book fans, and every last one says that it is "definitely" his shield. It is partially under construction, but you can see the red, white, and blue rings around a circular object with the "half-built" star in the middle. Just wanted to let everyone know this was out there because it is a VERY cool easter egg for fans.

Anyone else notice the cameo? Gotta love how Marvel keeps injecting different character hints into their films.
