I've used something like this for showing supplementary information when a user hovers over an image. Think Dribbble.

We're currently using something like this for in-app help on my company's SASS offering.

At the bottom of the page there is an example of using it to highlight the areas of the page the user can customize .

That example probably belongs near the top. It wasn't clear to me at all what the usecases were until I got to the end.

Thank you! I brought it closer to the top :) http://ellekasai.github.io/purplecoat.js/

Could also be useful for interactive walkthroughs of interfaces.
