Videos or Animated gifs of the portals wanted

[theinfamoustim]

I was wondering if anyone is able to help me with this. This seems like the best place to ask. I only own the console version of portal, so I don't have the ability to do the following myself.

I'm looking for either two individual videos of the orange and blue portals or two animated gifs of the two portals.

If they are gifs I would prefer a bigger size, something around 480 x 800 or bigger (if bigger, preferably something that would be easily cropped or shunken to 480 x 800). If they are videos I would rather it be in HD with no grain. I'd like them to NOT have Chell's arm in the pic, if possible. Just a clean close up of the two portals fluctuating as they do. The videos/gifs would only have to be around 30 seconds each.
