Don't peek

Hey, go over here and see if you can guess the answers, but don't read the first post where they are listed. First, scroll down to the pictures below.

I've been watching the project since the beginning (what a great idea!) and happened to be in the right-place-right-time on the final day, refreshing my browser like crazy and was able to get my answers in quickly. I still had two wrong, one of which I figured out pretty quickly but the other was a puzzler. See how you do.
