My three website picks

The Lost Worlds Fairs

http://lostworldsfairs.com/

I love the theme of this project, to highlight one feature of HTML in three exciting ways. Try resizing your browser while viewing any of the three examples to experience the dynamic nature of each interface.

Design made in Germany

These Germans sure are impressive. This design portrays a clean aesthetic with clever accents that changes as you scroll. This sort of attention to detail always inspires me to view source and see the magic behind the markup.

Mulheres Barbadas

I believe this portfolio site achieves a good balance between creativity and usability leaving the user with an interactive and tangible interface while still providing high quality content.
