This project homework is about a secret. I hid a secret on this website and I believe you will try to click these cards in the middle. After you try all these cards, you will find none of them is the one you are looking for. But if you move your cursor to the whole screen, you will find something somewhere. I was inspired by the east eggs in the early games, that you need to ignore the instructions from the game to find the hidden east eggs in it.
