BLOXcon

SOLD OUT: If your kid's a coding whiz (or wants to be one), head to the Intrepid this Saturday for a massive convention of hackers and computerphiles. The day involves a presentation on the mainstage (ticket holders can choose whether they want to attend the 9am, 11:15am, 1:30pm or 3:45pm show) of ROBLOX executives in which they'll explain new developments within the company and hold a Q&A session with guests. Meanwhile, kids can visit the R&D labs (between 9 and 10am it's open to all, while from 10am–4pm you'll need a reservation) to play with ROBLOX developers, or bring their laptops for a Hackathon (10am, 1pm and 4pm). Ages 8 and up.
