*To help keep this contest fair, we’ve elected to use an IP address-based poll. This means that if you are voting from an office or network setting, not everybody will be able to vote. We apologize for the inconvenience, but we hope you’ll encourage coworkers to vote from their home computers. And as always, we reserve the right to disqualify a photo if we see any voting irregularities.
