Need a break? Check out LinkedIn's version of Tetris, DropIn. The game, which was developed during a Hackday competition, uses blocks comprised of your contacts' profile pictures and LinkedIn "in" logos.
To play, log in to your LinkedIn account and visit LinkedIn Labs. Much like the original Tetris, DropIn uses your keyboard to rotate and place the blocks. Hover over a picture to review the contact's name, job info and latest status update. If your boss asks, you're networking.
