Okay kiddo, so the Planetary Collegium is like a school but for grown-ups who want to learn about something called "new media art."
You know how you can use your iPad to play games and watch videos? Well, grown-ups can also use technology to make really cool art. And the people who teach and study this kind of art at the Planetary Collegium are some of the best in the world!
The Collegium is kind of special because it's not in one place - it's all over the world! The teachers and students meet online or in person in different parts of the world to learn and create. It's like they have a big family, but they live in different houses all over the world.
They also do something called "research." That means they ask questions and try to find answers about new media art. They might study things like virtual reality or how to make art with robots.
It's like a really cool club of grown-ups who love technology and art and want to learn more!
