I loved couriers. You had this transfer of physical information happening throughout the city and the world. Someone picking up the package, putting it in a bag, going somewhere, taking it out of the bag, giving it to someone else. I thought that was so cool. I wanted to map it, to see that flow on a big screen.

Constraints inspire us in how we approach the press, how we approach business relationships, how we do everything.

Make every detail perfect and limit the number of details to perfect.

Twitter was around communication and visualizing what was happening in the world in real-time. Square was allowing everyone to accept the form of payment people have in their pocket today, which is a credit card.

The idea of Twitter started with me working in dispatch since I was 15 years old, where taxi cabs or firetrucks would broadcast where they were and what they were doing.

My goal is to simplify complexity.

I fell in love with flora of all types, especially ferns. Loved the sparse structure and repetition of shape - almost fractal.
