Don't ask what this is, or what it's good for, exactly. Perhaps try staring at it in your cubicle repeatedly to achieve some kind of pointless, slightly disturbed/annoyed Zen state—if one can be annoyed in a Zen state. So maybe that's the message here after all. And if you don't like Sheryl, try Jim Morrison or Nicki Watson on for size. Anyway, thanks to MC Glenn for this one.
