Panel Clock

A small theme that incorporates a minimalistic analog clock image. This looks a bit naff when used for a large clock, but is much more clear and crisp than the default when small (primarily, in a panel). The fallback theme is Air, but this should be able to be spliced together with any other light-coloured theme via the 'Desktop Theme Details' settings page.
