Picture of TwitMap: Topographical Colorado Twitter Map

 
TwitMap

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 .

WOW You have blown my mind with this idea, I just joined the site, browsed around didn't click on projects properly, then saw this and I had to check it out.

It's a brilliant concept and what a way to use the open source Arduino stuff.

Cool idea, good job!

Where did you download the Topo of your state? Please list a link.

I found it through Google Image search. I just added a link to a zipped folder of my images/vector files on the 'getting the map ready for cutting' step.
You can also download free topo maps from the usgs.gov website.
Excellent project!
