Chris at the Tourney of Logos has done a solid job all off season covering the RBK Edge change over and keeping fans involved via polls and other user-created-content requests.
At any rate, he's got a Southeast Division concepts post that leads off with a Lightning design that I myself have sorta pondered but have never been able to pull off.... It's a very modern design of the Lightning crest that eliminates basically all we know.
