I've also been playing around with the background look of the blog and gone for a nature theme (for now!). Hope you like it.
Also, I've just been introduced to Dropbox.

It is a free file sharing program you can download off the internet. You can use it to share files with yourself or others across multiple computers and mobile phones. We are planning to use it in our department to share files with colleagues without having to email. This will be useful when sharing large image files. I don't know whether we are covering this in 23 Things, but check it out anyway.
Dropbox replaces:
- Emailing file attachments to yourself and other people
- Using USB drives to move files between computers
- Renaming files to keep a history of previous versions
- Complicated backup software and hardware
