This website is very interesting. The website description goes like this: "Imagine an object, and our artificial intelligence program will guess the object you imagined by asking simple questions." If the program cannot figure out what you are thinking within 20 questions, it will admit defeat. I didn't quite believe it at that time, so I tried it myself. Let's go with "buffalo," and then I answered its questions one by one. These questions were all very simple, and options were provided. After 20 questions, it gave the answer, which was indeed "buffalo." Amazing! Haha.
