Interface design can run the gamut from blowing chunks to blowing your mind. But great interface, fueled by a great concept, can take you to a very happy place.

This next one is from KDDI, and it will blow your sprockets. The interface is in English and Japanese.
If you get bored at looking at this site, click the 'View Archive' button. Sweet gravy.
Lastly, this one from 'Publicite: Communication Responsable' may not look like much from - but it's a completely flash-enabled experience where you can move around content modules (including video) - resize, delete etc. Very nice.
One word of caution: it's in French. Mais alors, c'est magnifique.
