VR birthday card (Quest 2)

I had the idea of creating a VR birthday card for my wife and would love some suggestions how I could do that. The idea is to make a VR space with decorations and photos and some greeting where she can spend a good 5-10 minutes looking around and exploring. Maybe overlay it on our existing living room or something or just create a new smaller space. Anything is on the table and I’m looking for inspiration and some advice on how to achieve it.

So far, best idea I could find is using Gravity Sketch but would love to hear any ideas or suggestions 🙏

Thanks!
