I like the sofa thing
...but I'd like to be able to upload a photo of my living room and have the computer place an item of furniture in the photo for me, to scale. With the option to move it around. A little limited I know since it's a 2D photo, not a 3D model of my room. But it should be do-able. Modern image processing should be able, possibly with some user interaction, to identify the walls/floor and their angles.
This would be especially useful of on-line sales since it's difficult for many people to visualise furniture items in situ, especially large ones.
Biting the hand that feeds IT
