Crazy Tile!

What do you think about the new tile fad with busy and colorful tile on the bathroom floors, on the kitchen floors and on back splashes? I love some of it and others I could do without. I think the bright and colorful backsplash is pretty, but I am not sure that I could pull it off decor wise. I love the grays and white designs for floor tile in the bathroom or for the kitchen backsplash though. Which one is your favorite?
