Movie clip Obsidian logo thingy in beginning of Kotor 2 was kinda simplistic, not in anyway bad, but obsidian(black glass vulcanic stone thingy) is kinda too cool not to be used.
So my proposition for Obsdian logo movie clip would be black vulcanic stone(almost glassy) that reflects some moving light source until it reflects the light straight to camera blinding it for moment and then just white text on black background: Obsidian Entertainment.
You can post better ideas if you got them.
