You hear all the time about the importance of scale and proportion in design — making sure the elements of a room are harmonious and work according to established and unassailable principles of design, such as the Golden Ratio. Coffee tables, as the familiar story goes, should be two-thirds the size of the sofa and yada yada yada.

What pleases the eye, of course, is subjective, and not everyone likes a pat solution to life's sticky problems, or an overtly happy ending. Instead, choosing one large scale item creates drama within a room and plays interesting tricks on the eye. In the photo above (from Design*Sponge), just look at how this blue behemoth of a lamp towers over the moss green chairs. Some will recoil in fear at the idea, while others find the play on size refreshing. (Okay, and the colors are pretty badass too.)

So this post is for all you rule breakers out there. The wicked witches of the design world. Or simply those who want to experiment with something new on their own.

The following items work well in large scale and, done well, can poison peoples' minds for the expected.
