I love your brain so much; this is perfect. It allows students to apply what they've learned and thought instead of simply regurgitating everything back.

I still remember some great assignments from college where we were allowed some freedom and some creativity within the parameters of the assignment, but still allowed us to apply what we'd learned and show that we had.

This is brilliant; I think your students are going to love it.

Also, I have a couple of questions/ideas if you're looking for input into the assignment.
