Pi Day

Happy Pi Day (3/14) - here are a couple of related mapping projects. The Pi Project is a series of hand-casted sculptures of each digit in the pi sequence.

This project "will one day be recognized as the largest art installation in the world using data visualization and sculpture, centered around the infinite number sequence of Pi." The numbers are shipped around the world-here is an interactive map of their locations. You can hover over each number to see its location and sequence within Pi's digits.

Martin Krzywinski is a scientist and data visualizer who has created many Pi Day visualizations. This year's version involves road maps.

I'll let the author explain in his own words - full details here

City strips are horizontal arrangements of patches of roads sampled from a city. The order of the patches is determined by the digits of π, which are used to select regions of specific density of roads. 

No color—just lines. Lines from Marrakesh, Prague, Istanbul, Nice and other destinations for the mind and the heart.

 Last year he created an imaginary star chart using successive series of 12 digits from pi to define latitude, longitude and brightness. The stars are grouped into constellations honoring extinct animals - our evolutionary ancestors. Here is an example - the artwork can be purchased here.
