book change?

During class when everyone picked a book they were reading and doing the midterm report on, I had picked Turtles, Termites and Traffic Jams by Mitchell Resnick. But, I have been reading through How Nature Works by Per Bak and decided that I like this book more than Turtles, Termites, and Traffic Jams. I was wondering if someone in class is also reading this book for the midterm project and would mind if I used it for my mid-term project as well...
