Simon Long has blogged over on raspberrypi.org about an upgrade to the desktop environment of Raspbian, the standard distro for the Raspberry Pi. There are loads of tweaks and lots of polish including, but not limited to, theme background photographs, new icons and changes to the main window style. Perhaps the biggest changes are those involving installed packages with both remote control software RealVNC and the Chromium browser now included by default. Full details and instructions for installing the updates onto existing images can be found here. To download a fresh copy, visit the Downloads page.
