Impressive visualization, for sure. But a honest question: What are real use cases of such a representation? I mean, can (and will) this be used in a productive manner for solving what kind of problems?
The only use I can imagine is to use it to write a guide on the available software. You can pick from the image clusters and make them into chapters in your guide or something like.
Seems like a very useful way to navigate on a large touchscreen.
