Ian Li just won the Carnegie Mellon Smiley Award for Grafitter

, a web-based twitter visualization tool.  By using his special hashtag syntax, you can use twitter to record several variables about yourself, such as weight, mood, motivation, and foods eaten.  Then Grafitter offers an easy way to analyze and graph the data, turning Twitter into a powerful data acquisition system for information visualization and datamining.

“Grafitter would allow individuals to better understand the kind of content they have been producing and understand the patterns in their lives for any behavior they use Twitter to report on. It also allows this easy sharing of information (the main benefit of Twitter) with others to be made that much more valuable, as they can also see and identify patterns and comment back,” Dey said.
