Kartoo is a visual search engine that is definitely starting to turn heads.  The visual map cleanly uses Flash to visually represent rankings and relative weighting of sites based on search keywords.  Just type in “Sean Alexander”, “Chris Pirillo”, or “Robert Scoble”.  You'll see what I mean.  What it lacks in speed, it makes up for in context.

[Update] And along those same lines for Music, check out www.musicplasma.com which is a great example of WM Player extensibility.
