It’s the 100th birthday of the National Park Service and tonight, there are some fancy going-ons in New York City. Most exciting might be the ability to control the color of the spire of 1 World Trade Center using a giant digital circuitboard in Brooklyn Bridge Park. To change the color, participants have to collectively solve interactive puzzles. Even if you can’t make it, EarthCam will provide views of the New York City skyline from the Statue of Liberty.

The festivities at Brooklyn Bridge Park start at 1pm and go until 10pm tonight. There are some notables involved in this centennial celebration, including DJ Questlove who will perform from 8 to 10pm. Bill Nye the Science Guy will be giving opening remarks at 7:45pm and you can find the full schedule of events here. The New York City centennial celebration for the National Park Service is part of a broader initiative, #FindYourPark/#EncuentraTuParque movement, which included a virtual park circuit across the country.
