Worlds Fair Nano, New York

World fairs have always beckoned crowds to see the latest in scientific gadgetry and glean glimpses of the future. But at Worlds Fair Nano, previous technology, including the advent of the monorail, is dwarfed by mind-boggling displays. This two-day buffet of futurism is filled with interactive exhibits, live art, TED-like talks, music, and more. Here are a few highlights:

• Interactive Exhibits: Inside The Technology Playground, you'll play with (yes, actually touch) immersive virtual reality from Piranha and wearable mood controllers by Thync, track dog emotions with DogStar Life, fly XCRAFT's camera drones, and (virtually) ride a FUSAR's smart-helmet motorcycle.
• Futurist Talks: Hinge CEO Justin McLeod talks about "The Future of Dating," WayUp CEO Liz Wessel chats about "The Future of Hiring," New York City's first ever CTO, Minerva Tantoco, talks "The Future of Cities," and other experts describe the futures of art, advertising, learning, social media, music, storytelling, and even world fairs.
• Art and Music: Be immersed in exhibits such as Cloud (an interactive thunderstorm simulation) and the nostalgia-stirring KidSuper, and groove to a soundtrack from Levin Kali, The Josh Craig, and Kess.
