This experiment is the first iteration of a physical and visual interface for tangibly accessing archived sets of information—in this case using radio station DJ's playlists.
Larger objects are embodied with a specific DJ's playlist. These are meant to simply illustrate that one could use any object and associate it with an archived set of information. The smaller sliver-like objects are meant to represent and embody the search "node" or information you enter with. These can also be reassigned on the fly.
I imagine that one could use any of their personal favorite objects, such as mobile device, stuffed animal, or some other personal object with invested meaning.
