Decorating Design Tool

Here's a decorating design tool on iVillage.com that allows you to see what a room would look like before you do it. While it's not your exact room, it does give you an idea of colors, flooring, and furniture. (One drawback is that the countertops can only be a color, not a granite or stone, but still its an indicator.)  Check it out and let me know what you think of this. Helpful or not?
