Quite simply the most well designed specimen I've found in this field of to-the-point, single page, personal presentation sites. Nothing extraordinary about the interaction here, but the presentation is 100%.
There's no denying that Paul Kelley aka Ch3mical has made himself a great single page portfolio site. He pulls it off by combining a straight forward text based presentation with a very clever presentation of external links. Via @ozlarsen.
Zerply recently flew in Luke Beard from the British countryside to help them out with their new site design. They just launched the first results from their collaboration, and it's pure gold. My favorite parts of the new home page is the animated "User Login" button and the dynamic "Face Box" combined with a clear description and call to action. The use of Adelle via Typekit also works wonders.
