I'll do you one better.
Find the video online, do a screen capture of any image you want as your background on 360 dashboard.
Save that image to a media card in your camera.
Hook up the camera to the 360 via USB connection.
Open the image through the media reader and use option to set as background.
I'm sure if you look hard enough on google you can problably find a screen shot of any halo image you really want. All this for 10 minutes of your time and no money
