To celebrate the 155th anniversary of the Pony Express, Google came up with a game as its celebratory doodle. I'd have posted this last week, but I was too busy trying to get the pony to stop being totally unimpressed by my efforts (all that was lacking was eye-rolling).... My reflexes (and the number of letters safely delivered) have improved, though, and we've moved past the pony applauding and into jumping up and down territory. My best score to date (and that only once) is 75 letters. Top score is apparently 100 letters.
Just a word of warning if you play this at work -- turn the sound down on your computer, or people are going to want to know where that sound of galloping is coming from. :-)
