There were a couple of small issues along the way - a bit of code

I have implemented Good-Looking Tooltips, using the excellent technique by Robert Nyman.

There were a couple of small issues along the way - a bit of code I added to the site's JavaScript when I was experimenting with XHTML was causing some trouble, and < and > were being treated as HTML rather than as characters. Robert kindly helped me work out the kinks though, and now it's all up and running. For an example, hover over this text.
