This kind of thing has got to be the future of files and folders so long as we have files and folders: the Innolab 3D File Manager from Adam Miezianko, Kristopher Rambish, Karen Fung, Zavnura Pingkan at Boston University. (Thanks, visualcomplexity.com)
This design is like a ferris wheel which organises contents by their relationships rather than their physical position on a hard drive. Each spiderweb thread marks the ties between folders holding contents related to the open file folder (center, in purple).
The file manager runs on Linux. It’s actually old: 2003, so something of a shame this kind of thing hasn’t caught on. The closest, I guess, is 3D Topicscape and perhaps WinFS, the storage system that was dropped from Vista back in 2004.
