Ohio is a Piano
OK, I think I think we have a winner for coolest map-thing-of-the-year. Andy Woodruff at Cartogrammar has created a musical map:
Last month, as I was driving through Ohio to collect my final three counties in the state, it dawned on me: There are 88 counties in this state. There are 88 keys on a piano. I don’t know anything about music, but holy crap, I have to make a map based on this coincidence.
And so I did, bit by bit, gradually descending into madness in the process. It has no purpose, really, apart from being an experiment in some sort of weird artistic musical cartography. Ohio is a piano. Check it out. (It’s in Flash.)
Each county on the map is keyed to a piano note. Play the OhioPiano by plucking a county, or pull together a string of notes by charting a route between two cities. Change the note of each county by ranking them, highest to lowest, by a demographic (such as population, ethnic groups, number of farms, etc.). Arrange them just right to play a tune, or use one of the pre-programmed songs.
Woodruff says he's "gone off the deep end, musically and cartographically", but I say "Go Andy" you are now my carto-hero of 2009!
