This looks like a big idea.
Features that come into my mind:
-Locations where the "thing" is currently available.
-Advanced visual search of "things" by drawing dimensions (I need something of this shape and color, made from that material).

I love your idea about visual search! We already have idea of visual "ruler" to mark known dimensions directly on photo.
