I've been asked by my boss to make a semi-functional mockup of a webapp using flex. He has requested that it looks as "WOW!" as possible. The built in flex components are pretty basic. Are there any libraries out there with nifty looking components? The only one I have found is flexlib, which is awesome, but I still need more components. I'd also like to find some nice looking charts as well.
p.s. My boss is one of those "OOH IT'S SHINY!" kind of guys, so the more unnecessary bells and whistles the better.
