Couldn't you just take your glasses off for Tron? It's not really a ride about seeing but more about feeling. That initial blast is pretty much the greatest thing Disney has ever done, at least for me.
Perhaps I'm nitpicking but I don't see Hyperspace Mountain as novel. It's just Space Mountain with some added gimmicks.
Someone else mentioned the Iron Man attraction at HK which I find to be extremely lame. There is a reason it's always a walk on ride, something you use to kill time for something else.
