The Shuttle project began over a year and a half ago, aiming to beautify the WordPress administration panel. With the help of Khaled Abou Alfa, Michaeil Heilemann, Chris J Davis, Joshua Sigar, Joen Asmussen, Ryan Boren and Bryan Veloso (all top-notch designers), Shuttle has finally taken off. To get a better sense of what Shuttle is, I recommend you take a look at some of the screenshots. Shuttle is not a plugin you can download, instead it will be integrated into the next version of WordPress. The Shuttle team has worked closely with Matt Mullenwegg, lead WordPress developer, to seamlessly incorporate their efforts into WordPress.
