Taglines is a visualization tool prototyped at Yahoo! research labs to see tags with floating thumbnails along a primary axis of time. It’s quite a neat zeitgeist kind of interface.

Among other things, you can click and hold on tags or thumbnails and of course, change the speed which you “move” through them over time. This project was discussed at the excellent tagging workshop at the WWW2006 conference last week in Edinburgh, Scotland. The paper describing the system: Visualizing Tags over Time by these authors: Micah Dubinko, Ravi Kumar, Joseph Magnani, Jasmine Novak, Prabhakar Raghavan and Andrew Tomkins - all from Yahoo! Research, USA.
