Looking at those pictures also gets you thinking aobut how the meaning of art can change over time. Good art, in my opinion, won't always say the same thing to you. It will evoke different thoughts and emotions based on life experiences. What those shuttle pictures said to us before is not what they will say to us now.

That isn't bad, but usually the meaning of pictures changes over longer periods of time. Right now, it is kind of like looking at a double exposed negative. I get conflicting feelings.
