Here's some background pics (well, they've got potential anyways) that I made...lemme know what ya think... United - 1 United - 2 United - 3 Edit: Photobucket resized 'em, so that's why they look small...they're actually full-screen...
That first one looks like its going to bounce up and down as if with hydraulics. Looking good but the 2nd one, the jet blast didnt come out that well.
