Lava Lamp – A lava lamp isn’t terribly interactive but it certainly does add a pleasant kind of movement to the room as well as a soft glow that will bathe the room in a kind of futuristic light. At the same time, as the balls of lava move, so the lighting will change in the rest of the room. Custom Aquariums – Custom aquariums can be built to fit suit any specifications and any décor, and will add a lot to any room. While water falls or lava lamps give you something constantly moving to look at, custom aquariums bring life to your room and all the fascinating unpredictability that comes with that. Here you can choose different fish, different ornaments, or whatever else you want making custom aquariums completely unique, and then watch them interact for hours. For an individual this provides a certain comfort and company when you’re working or relaxing, and for guests and visitors it’s interesting to watch and may even include some exotic fish they’ve never seen before. At the same time you get the benefit of the movement, the light refracting off of the water, and the light trickling sound that custom aquariums create and that can bring a lot more life to the room as well.
