Concept artist Fabian Lacey designed many of the props for The Avengers, including Hawkeye's bow and arrows, Loki's sceptre and staff, and Tony Stark's bracelets. And Lacey has kindly released several of his concept designs for the film.

You can see even more concepts and detailed designs at Lacey's website, and lose yourself in the warm blue glow of all that speculative technology.
