We Feel Fine is an exploration of human emotion, in six movements by Jonathan Harris and Sep Kamvar. The project scrapes the web for statements made "I feel ____" or "I am feeling _____." These statements, and other data regarding the source of the statement, like location are used in the We Feel Fine visualization. What is not totally obvious is that We Feel Fine has an API allowing you to connect into their database of feelings. Check it out!
The Social Collider reveals cross-connections between conversations on Twitter, creating beautiful, physics-reminiscent graphics of the threads of conversation. Moritz Stefaner cited this as an inspiration behind his Revisit project. Credits for Social Collider go to Karsten Schmidt and Sascha Pohflepp.
Revisit by Moritz Stefaner was used throughout Eyeo to show the real-time and recent twitter feed on #eyeo. It's a beautiful, and ephemeral visualization, pulling tweets dynamically, and revealing interactions between users tweeting on a topic (or multiple topics). Use revisit for your next event or twitter community, or just to watch the ever flowing stream of twitter from your browser.
