If you’re familiar with Custom Corners for Moodle 1.9 you’ll know that it’s a simple and straight forward theme that provides a greyish color scheme and rounded block corners.  The theme has been retooled for Moodle 2.2 and is now available for download.  Originally created by Urs Hunkler, the update comes from Mary Evans.
