Nissan, best known for building cars, built a Facebook application for Habitat for Humanity to help promote green building and raise funds.

The Habitat for Humanity Charity Game invites players to type in commands for the volunteer builders to follow. Without revealing too much, let’s just say that whenever you have a giant penguin returning an item that was thrown, hilarity ensues.

The top 100 scorers will receive personalized videos from Nissan, in which volunteers at a build site will pound a nail in the name of each winner, as well as Nissan T-shirts.

On the serious side, participants in the Habitat for Humanity Charity Game are then directed to the Habitat for Humanity website, where they can donate money, volunteer to participate in a build, or take action in their communities.

Nissan said it has been a Habitat for Humanity partner since 2006, with contributions including $7.5 million in grant money and donations, 50 homes built, 104 Nissan vehicles donated, and more than 5,000 Nissan employee volunteers.
