Hey @Icky ,
Welcome to the Babylon family. Awesome to have you here!
Sounds like a fun project!
A piece of low hanging fruit in your project would probably be to think about a skybox. Here’s a link to a playground with a fantastic nighttime skybox done by @PatrickRyan.
Beyond that, it sounds like there’s a lot of different cool things you could do with a project like this.
Here’s some helpful info to get started on how to do selections in Babylon:

Also - @syntheticmagus links to some solid examples on how to blend camera control and mesh picking in the scene in this forum post here:
Hopefully those help you get started a bit on your Babylon journey.
Also, if you haven’t already, I’d strongly encourage you to check out the Babylon 101 documentation located here:

If you’re anything like me, it can be tempting to move past some of this intro stuff in an effort to get right to bringing your vision to life, but I STRONGLY encourage you to check out the 101 docs. It’s SUPER valuable!
Cheers!
