There's lots of potential for Genie 3 and 3D Portfolios

Imagine a 3D world you can explore that has links and 3D representations of all the projects you made over your life. It would be nice if there was some API of sorts that lets you connect certain actions in the virtual world to the physical world, such as hovering over a lectern will open your resume, or standing in front of a hallway and your 3D model designs will pop up as you walk down the hallway. You could create a virtual library or a place to store all your notes and ideas.

Another interesting use case not related to 3D portfolios would be if you connected your world to a bluetooth controller like the ESP32 and control smart appliances in your home, so when you flick a lever in the AI-generated world, it turns on/off appliances in the real world.
