Two of the very best visualization designers and researchers around today, Fernanda Viegas and Martin Wattenberg, have started a new website, titled Hint.fm [hint.fm] or it exists much longer and I just didnt know. The website collects their past presentations, publications, exhibitions, press coverage, and all of their works, of which Many Eyes, FleshMap, and Phrase Nets are just a few.

Most projects are remarkable in their apparent focus on combining the aspects of beauty and story-telling through the presentation data. As they state themselves in the colophon, “Unlike … traditional uses, we believe visualization to be an expressive medium that invites emotion.”Two latest project stand out. “Flickr Flow” is based on a large collection of photographs of the Boston Common taken from Flickr.

A specifically design algorithm calculates the relative proportions of different colors seen in photos taken in each month of the year, and plotted them on a wheel. The resulting diagram picks up the ebb and flow of seasonal colors.Web Seer” attempts to visualize peoples innermost thoughts by using data originating from Google Suggest the drop-down box that guesses your search query while you write.

The interactive tool contrast two separate search queries, as it highlights the commonly shared and opposite suggestions proposed by the Google algorithm. The arrow thicknesses show the number of web pages for each question. Insightful examples include “are Democrats” versus “are Republicans”, or “shopping for men” versus “shopping for women”. Both authors describe a qualitative analysis of the resulting graphs at a recent op-ed “op-chart” in The New York Times.

Caves are some of the last places on the planet left to explore. Though caving is relatively safe, if something goes wrong deep inside the Earth, a rescue can take days — in part because cell phones and walkie-talkies don't work underground. But a remarkable teenager in New Mexico has invented a device that may significantly speed that process with the ability to text from underground caves. The young man's invention may have other applications, as well.

Underground Transmission

Alexander Kendrick, 16, won the 2009 International Science Fair for inventing this cave-texting device. The award got the teen from Los Alamos, N.M., a new computer, a trip to Switzerland and $12,000.

A cave radio that allows you to beam data to the surface rather than visiting it in person can be extremely valuable. It could save the cave.

I wanted to find out why this thing was such a big deal. The next thing I knew, I was hanging from a rope in the bowels of the Earth and groaning under my breath.

I was with a team of cavers in Carlsbad Caverns National Park in New Mexico, heading 1,000 feet underground to test Kendrick's invention.

The device is something like a computer attached to a ham radio. It transmits data using low-frequency radio waves that can penetrate rock more easily than high-frequency transmissions, like those in FM broadcasts.

If this test succeeded, it would be the deepest known underground digital communication ever to take place in the United States.

The Difference Between Life And Death

Why would anyone want to text from nearly 1,000 feet underground?

Here's why: In a 1991 New Mexico cave rescue, it took 170 people four days to save a woman with a broken leg. The rescue team had to lay miles of telephone line in order to stay in touch with the surface.

If they'd had Kendrick's radio, the rescue time may have been cut in half.
