Beneath your feet. A friend sold her house last year and the hardest thing to leave behind was the kitchen floor which she had so beautifully hand-stencilled. Stencilling is a great way to adorn your floors. You can go big or keep it small and detailed. The photo above is from Domino magazine where you can also find a detailed floor stencilling "how to".
Paint by numbers in your nursery (found here along with tips and instructions for giving your floor a facelift.)
This floor stencil is so striking that, for the first time, our eye didn't immediately gravitate toward the Eames rocker (see more at the Stencil Gallery).
