A friend of mine had access to an app called Spireworks, which allows you to modify colors of specific buildings in NYC through charity donations. I had only heard about this through friends and wasnt sure if it was even real until I experienced it in person for the first time. Definitely a bucket list moment after living in NYC for 9 years! Only took 9 years of living in NYC to experience this bucket list moment. Woman controlling the light on the one world trade building from a phone app
