For the web design class, we worked over night before the presentation day. It was crazy but it worth. Working with people with nice design sense is fun, and I enjoyed the way we cooperate: one went first for the mock-up, the second one did the front-end coding, and then I did the last implementation part. Staying in the library over night, I found it was really quiet and the cafe was still open. Fortunately, we finished the work, and delivered today.
