The Spry Team launched a new preview today: Tooltips. I'm feeling a bit lazy today so I won't go into too much detail, but the link above will show you both examples and documentation. I have to say I really like how they did this. It is fairly simple to setup and I love the use of effects. Here is a quick demo I did:

Like most other Spry widgets, the basic work flow is:

• Create your items (in this case, you have one item for the tooltip and one item that launches the tooltip)
• Use a line of JavaScript to "turn on" the widget

I'll let you view source on the demo to see how little code was involved.
