Cool Bulletin Board idea to "spotlight" a student or famous person. I would do both. Maybe every week a different actor, playwright, designer, etc to research to extra credit or a weekly report, and every now and then a student, to make them feel special having been up on the same wall as a big name.
This crocodile bulletin board display reminds me of "The Enormous Crocodile" by Roald Dahl. Children would get a kick out of you taking photographs of them, cutting them out, and placing them inside the crocodile's mouth like in this bulletin board display example.
