Oblivion Polymorph Mod
Via Kotaku, a post on the Oblivion forums on a polymorph mod for Oblivion. The Kotaku story has a video attached, showing the shapechanging in action with a rocking musical background. The mod seems awesome, but I'm not sure I agree with poster Eckhardt's commentary: "This could be just the thing for me to forget how unbearably stagnant and boring I ultimately find Oblivion to be: the ability to transmogrify into huge ogres, gigantic walking sticks and carnivorous cephalopods."

BTMod is I think the one you're referring to. A 'must have' mod for Oblivion really.
