With 340 students and 40 undergrad teaching assistants (UTA), decided to make a simple Amazon logo cookie. The students were busy writing a recommender system for movies, books and restaurants. I had used Amazon as an example that uses a recommender system to recommend books from people who rate books in a similar way to the way you rate books.
