I finally changed the default design of Eccentric Eclectica. I basically combined the default clean style from MovableType with some of my own ideas about the sidebar, dropping the calendar, rearranging the lists of recent enties and the list of archives. The change is pretty simple and already I can see some tweaks I might make over the next few days.
One credit where it's due for the use of Adam Kalsey's ArchiveDateHeader plugin.
