The shuttle project which began back in dec 2004 was finally launched to make the WordPress administration look better. The people behind this project are Khaled Abou Alfa, Michael Heilemann, Chris J Davis, Joshua Sigar, Joen Asmussen, and Bryan Veloso. This project will not be released as a plugin, instead Matt Mullenweg (lead developer of WordPress) will be incorporating these mockups into the official WordPress releases in due course.
