It has always been a challenge for me to make a piece extremely simple and minimalistic yet beautifully designed. I have found a site showing 25 Beautiful Minimalistic Website Designs. All of these site are very simple and have very simple navigation menus.
I really like the Ben Hulse Design website (pictured right). I like that website is mainly image based. The navigation is very simple. The rollovers are very simple and just show a colored line under the word. It is very simple but yet very elegant.
