Let's begin with the impressive website of NikeAir.

Click on "Run on Air" or "Ball on Air" so that you can play an interactive video of a girl/guy running. By using the keyboard you can launch for about 2 minutes very beautiful vectorial/3D animations interacting with the runner and it's just beautiful! With this website, you become a kind of VJ and at the end you just want to click on the Try again button. I think this application could be even more interesting if a sound would be launched in relation with an animation when a key is pressed. It would give more immersion for the user who could then become a DJ by mixing these sounds in live. However it's a Nike website, so I can understand that sound isn't the main interest for this brand.
I'm not a fan of Nike but I must admit this brand releases sometimes good advertisements like this one:
Really short, astonishing and pretty video of a young skateboarder who plays with changing the dimensional space and axes of the world just by chalking some lines on the ground.
You can find the making of here : www.nike.com/nikeskateboarding/
While we're talking about good commercials, I have to show you the Coloribus blog.
It gathers all innovative adverts (and as you can see in the category ADmirror, it's not easy to be innovative in advertising). I made a little selection here because I find really intelligent this new kind of adverts that adapt to the place they are showed, that use for example common objects we can find on the street such as manholes, streetlights and divert them of their first usefulness. 
WallDesign is a parisian shop allowing to choose your wallpaper online.
You can custom as you want your wallpaper by chossing the patterns, their sizes, their colors, add furniture and see the bill in live Sin bottom-right. You can even send by mail your creation to a friend so that he can say you have really bad taste (mine is here).
I like the design, the navigation and the features of this website, really clear and fluid.
