The layout of
http://www.madatoms.com is eye-catching. It is also easy to navigate. Those two concepts, when fused together make the website design great.
I went on
http://www.sonyericsson.com/xperiments/ and I really like the links on the top. Again they are pleasing to the eye while also being easy to use. They blend in nicely with the page.
Http://www.boingboing.net/ is a large blog. It has a cool seamless layout where things are spread out on a long page, but they seem to be grouped in a very reasonable way. The red links and black text seem to blend smoothly. The pictures are borderless and the titles look perfectly sized.
