Venture to the Kramer Electronics Facebook page, "like" them, and enter the "Adventures with HDMI" contest. If you already "like" them, then proceed straight to "Your Mission."
If you complete the puzzler successfully, and you'll be entered into a drawing to win an "Adventures with HDMI" T-shirt, which, as Kramer says, "will be the envy of all your adventuresome, T-shirt-loving friends."
The contest will be held from August 1 to September 30.
