From the developer:
A bright orange Start box, sharp gradients, and effective gray-on-gray accents make the theme--based on the company's Zune media player--a welcome change from the default blues and greens.
Not especially enamored of the default desktop wallpaper, which lunges away from the cool factor generated by the rest of the theme in favor of cheesiness, but that's an easy enough user customization
