I just came across http://wefeelfine.org/ - tracks feelings across rss feeds. I have only briefly looked at the app and methodology and I am not sure what goals it will accomplish, but it has some interesting ideas.
My first impression is that the overall UI makes me feel like I am interacting more directly with content instead of controls (including the hover based scrolling)
The rss snippets racing and hovering across the screen look like they are some sort of life forms with somewhere to go. A bit much, but kind of cool.
After looking at something like this, I can feel the neurons firing in the back of my brain - not really knowing where they are going.
