This instructable will show you how to make a 3D Map of Twitter data for the state of Colorado, but you'll be able to recreate it for any area that you wish.
This map is made out of multiple laser-cut layers of basswood and uses LEDs and an Arduino board to display what kind of Twitter activity is coming out of various cities in Colorado. We can display if Tweets from a given city are happy, sad, depressed or angry. We even have a Bieber mode!
We made this for the Things That Think class Spring 2011 at CU Boulder. We're Paul Heider , Buck Heroux and Ian Smith .
