MyFourWalls is an easy-to-use furnishing planner that allows you to dramatically change the design of your rooms and then take a virtual tour in real time.
Moving to a new place and you have no idea how you will find room for all your belongings or you just want to give a new look to your apartment without spending days moving your furniture from one place to another? Then, MyFourWalls is the perfect application that will make all your headaches go away. Although MyFourWalls is still in beta stage, it gives you the possibility to do all the rearranging comfortably on your computer and only when you are completely satisfied with the result actually move your stuff.
The entire process might take a while, especially if you have a lot of furniture because you must create a 2D/3D representation of your space and find the default items that resemble your own, but even so, it is better than actually moving them all around.
