This shelframe just shot right to the top of my list of "why didn't I think of that" ideas. About:
The shelves are designed to occupy a space normally reserved for a framed picture or painting, and they act so as to frame compositions of everyday objects.
The cable tension allow the shelves to support heavy objects while the silicone pads create a self-securing system that grips the wall as the shelf becomes loaded. This also means that the shelf does not tilt to one side if heavy objects are placed unevenly.
I especially appreciate the smaller details of the shelf like the semi recessed balls on the ends of the cable, and the joinery between the sides. For the record, this shelf and a monkey hook would make for the quickest installation ever.
Lots of pics after the jump.
