This does sound great but because I'm an idiot I assumed the title meant that they had installed a 20 story LCD display on the side of an old space shuttle.
Which I thought was pretty cool too.
But I think I've been watching too many PC gaming hardware review videos.
I read the title and literally thought "Huh how did they fit that inside the shuttle?"
It gets worse, I thought they installed such LCD display to virtually display the shuttle in real life size or something :) The importance of proper titles...
I thought the same thing.
And I think some of the advertisement screens in places like Times Square could easily scale to 20 stories. I don't think they're that big now, but I think they could do it with little trouble.
