I was uber lucky to have help this summer from two of my fave teenagers, Mac and Elena, who are high school students (though not at my high school). In exchange for soda, chips, and some community service hours, they helped me with a variety of projects in the library, including creating this awesome bulletin board.
I told them I wanted to put up a bulletin board over the students' printer where I could post announcements for the students. They asked if they could collage it. I said sure! I mentioned the announcements would be short, like Tweets, and they ran with it.
And here's the awesome end result!
