Picture it or video reality?

It´s all a question of creativity again. But I´m running out of good ideas.
Now it´s time for our final project. We have one week to plan it and four days to make it.
It´s group work. Our group consists of Nacho, Jaume, Juan, Leo and me. We had a first conversation with our assisting teacher: Lisa, she´s an artist. Then we had to brainstorm for hours, only interrupted for a modest meal. We decided more or less to do something with fotos, sound and/or video. An interactive map showing the "Faces of Malmö" together with typical sounds was one idea. Firstly we thought about writing a song (four of our group play the guitar) and making a music video, but we haven´t got enough time to deliver reasonable results. Now it could be kind of a dogma-short film or an absurd ad.
Tomorrow we talk to Lisa about it. Maybe we get some better ideas. Suggestions are welcome!
