Wired Magazine does these great "future of..." image competitions.
This "future of medicine" image struck me as a great project option. The prompt would go something like this:
"Design a medicine that would address a biological challenge a person might want to fix or enhance. Create an advertisement for that medicine that proves you have an understanding of the biological process & principals the medicine is designed to interact with. You may design a website for the ad, create a pamphlet, or a commercial to sell your medical innovation. No matter what format you choose you MUST illustrate or write up explainations of the scientific concepts related to your project."
