The Wizard World of Harry potter website has an award for the outstanding achievement in web development and you can see why if you check it. It is very interactive and has a mystery atmosphere related with the theme is about and which is good for the audience is directed.

48windows is a website created by Fahrenheit Studio (USA) which has won many awards and has collaborated with clients such as IBM, Warner Bros, among others . This is It is interesting the contrast the intro page has versus the index page, although still they keep the organic sea shell shape in a way to unify both of the pages. That shape helps to create a subtle but still distinguished background to help the composition be more dynamic.
This website is not as minimalist as other websites i posted, but still keep that fresh style i like. Also the website of the own studio could be another example of a flash website. It is very colorful, playful, fun and very dynamic but what i dont like at all is all the sound it has. I´m not against of having a little bit of noise when rolling over certain objects, but this one has too many. Check it out!

The Garden website, created by the Fishouse in Italy, has been done in Macromedia flash which i found it very creative, dynamic and very clean. Also it is intuitive what make it easier to go through it.
Turn on your speakers because it has some sound.

I like the idea of the intro being an interactive page in this website: Index Ventures. Since this website has a lot of information, it is great how clean, organize and simple the design is. Also it is nice how some little illustrations are introduced in each page, making the relation with the intro. Also, the color decision are great. In my opinion, all the colors work perfectly with each other.

The website has had many site hits and in my opinion it deserves it because it is very visually different and creative, dynamic and very consistent. Also it is intuitive and easy to go through it.
