A simply wonderful description from the Associated Press on Kim Yu-Na's world record-setting and gold-medal-clinching performance at the Winter Olympics:

There were simply no visible flaws in Kim's performance, from her skating to her expressions to that lovely cobalt blue dress. While other skaters slow down as they approach their jumps to steady themselves, she hurtles into them at full speed yet touches down with feathery lightness. Her connecting steps are like art on ice, and her edges show not even the slightest hint of a harsh scrape. Her spins were centered so perfectly the tracings looked as if they were made with a protractor, and she must be quadruple-jointed to pull off all those positions in her combination spins.
