Information Aesthetics is a blog focusing on the intersection of art and information presentation. It's chock-full of those cool arty projects involving databases, data feeds, graphs, scupltures, all that jazz. For example:

• Color Code is "a full-color portrait of the English language." Actually, it is a tree map of nouns, clustered by meaning, colored by averaging the pixels of images found via Yahoo image search, and then sized by intensity. I'm not sure it reveals much (except that flowers, food, and surgeries have characteristic colors), but it's always interesting to see old information presented a new way. It was created by Martin Wattenberg, who also did Map of the Market.
• Bitfall "is a physical water sculpture with 128 synchronized magnetic valves, so that a wall of falling water drops can be perceived as a graphical bitmap matrix."
• Spore 1.1 "is a rubber tree plant for which the conditions for life or death are controlled by monitored fluctuations in the stock market price of Home Depot."

There's plenty more where that came from. Go take a look.
