PlanetaRoom is a novel idea that I think won’t find too many fans - it is actually a helium-filled beach ball that floats around your home, complete with images of the earth and moon on them. An interesting point to them would be the ability to glow in the dark, displaying all the pretty city lights at night or a map of the stars. Each of these PlanetaRooms retail for approximately $20. Just make sure this doesn’t float into any ceiling fan that is turned on lest your “planet” experiences an explosion that resembles bits and pieces of Humpty Dumpty all over the floor.
