My prototype is 7" wide, 2" deep, and 6" high recycled from an old waterbed accoutrement. It is currently mounted with a simple gravity bond between the topboard and topside of my bedside tabletop. Previously, I had pinned it to other surfaces near the region of my designated sleeping surface. See link to protophoto.

A friend-of-a-friend came to one of my parties once who had patented, manufactured, and marketed a "Remote Control Tree' plastic lazy-susan device to keep your various remote controls organized. He gave me one and it worked well, except each remote it stored had to be fitted with double-stick tape mounted mounting hooks and the rotating assembly they attached to had to stand on a flat surface accesible to all channel surfers.
