A simple website of a contemporary art gallery in Paris (you’ll see, that’s very minimal): http://www.galeriecharlot.com/
Unfortunately i cannot show the backend, where most of the Yii power could be seen. I wrote a post in my (pretty new) blog: http://blog.estebanalmiron.com/2012/09/26/galerie-charlot-website-yiimuseo-sans/
Comments and criticism are welcome, of course.
