This art exhibit (in Seattle, at an event called Beatwalk) included a big piece of paper, some pens, and an invitation. Here are three youngsters, drawing. One of them is my friend's son, but it's only my phone's little video camera, so probably only his parents can tell. I don't know the other two.
The music in the background is a band, who were behind me. I didn't understand the lyrics at the time, but now I think he's singing "Yes we can, make it happen". And I really like it with these pictures.
