Those are the blazing hands of the current StarCraft II World Champion and by far the best player in the world, STX_INnoVation, participating in the WCG Korea Qualifiers. He's easily tearing apart a Protoss opponent with his unmatched Terran skills and rapid-fire decision making.
He probably doesn't even recognize that GomTV's own StarCraft II caster, Khaldor is behind him, capturing every moment. Oh and nice keyboard by the way, with that F1 key removed—no one's using it—you don't even have to see the game to know it belongs to a StarCraft player.
