Drag and Drop Blocks to Rearrange User Interface

This site features a drag and drop interface to rearrange the displayed blocks. You can drag any of the blocks on the left to rearrange them. Just drag them by their titles. The site will save the new arrangement in a cookie on your computer so when you revisit the page - they layout will be as you had configured them. Click here to learn how this was implemented.

Also in the works is a drag and drop layout module for the block administration in drupal. Click here to learn more about it.
