Interior design and decoration is a fascinating world. At least that's what decorators say while trying to convince their customers that there's more to furnishing a room than just randomly arranging furniture. I've never been much of a decoration fan, but I'm impressed by the amount of materials devoted to this topic: agencies, shops, magazines, books, even TV channels... and of course, software. So if you think your home needs an upgrade, take a look at these applications and don't be afraid to redecorate your life.
