Click for HQ
EDIT: it's been fixed and is now true 1080p. Just click the picture to see it in Picasa, where there is a magnify icon on the top right of the image. Clicking on that will get you the big size.
Blogger's being bitchy and not letting me upload anything bigger that 1600x900. However this does maintain the aspect ratio, and when stretched to fill your 1080p screen, it still maintains the quality.
