A website called The Establishing Shot just recently jumped on the Slingers bandwagon with us, and posted a review that can be found here. Look toward the bottom, and you'll see a Slingers poster created by a fan! The first official Slingers fan art.
Hopefully we won't have to wait too long for some official Slingers artwork - Mike Atherton, aka Sizemore, and Toby Moores are presently in Los Angeles "taking some meetings" with some fine Hollywood folks, who will hopefully give them gobs of money to bring the series to all of our televisions in the very near future.
In the meantime, do yourself a favor and go watch the teaser again here on Vimeo. And don't forget to become a fan of the show on Facebook. Their fan page can be found here.
