The Modi sofa is one of the more interesting stabs at modular furniture design I've seen in recent years. By altering the cushion configuration, you can basically create any type of seating you desire.
Plus, you have even more options when you add on additional units. The possibilities are nearly endless. The only snag is that the Modi is still in the concept stage—but it has all of the characteristics of something that could be a hit. [Moredesign via Trendsnow via Homedit via Hometone]
