I came across perspectv courtesy of Josh Catone on Sitepoint. It’s a very nicely implemented term comparison interface, providing News, Blog and Google search comparisons for up to five terms. Follow this link to open the page below. Let’s take a look:

All in all, a very well considered interface striking a good balance between useability and aesthetics.
