For me it’s about positioning data in a visually unique space, so when I’m browsing my file system trying to remember where I saved something, I’ll have the visual cues of form and pattern to help.
I don’t have an updated preview but I describe my reasoning more in a blog with screenshots of a year old 2D prototype.
I’d be very curious to know where your project is at, eventually I’m going to have to port this to Unity so it works outside of web browsers, but I really want to keep the cross-device compatibility, so I’m working on a data storage layer that can serve both (you guessed it, everything is in JSON)
