Ctrl + Alt + Del ... if only wearing the necklace restarted your day as easily as those keys restart your computer...
My best friend took the keys off of her old busted laptop... a small hand drill + a few jump rings ... and voila, a fun charm you can put on any old chain.
One of my friends calls it "the three finger salute." I call it perfect to wear to work where we have lousy computers that need to be restarted ALL of the time :P
