Jack Dorsey (@jack)
I've always been fascinated by cities and how they work. I want to visualize them, I want to see them, I want to play with them. I was inspired by New York City. If you consider NYC of all these entities just roaming the city, you've ambulances, fire trucks, taxi cabs and they always report where they are and what they are doing. If you can visualize that you can actually see how the city is living, breathing and what's happening.
