Design Inspiration: Painted Floors

Rather than, or I should say in addition to, covering the floor of your apartment or home with Flor tiles or flokati rugs, have any of you ever thought of painting your floors?  Perhaps not possible if you've got carpet, but if you're lucky enough to have wooden floors and an understanding landlord (or you know, if you own your place), would you paint your floors? I think I would.  I'm sure it's a bit of a headache, but if the results are like any of these rooms, than it's worth the momentary migraine. white floors Marie Olsson Nylander's home is gorgeous, with painted floors throughout, but this is my favorite room.  Look at that view! bright floors patterned floors So...what are your feelings on painted floors?  Yay or nay?
