I play the "mystery picture" game with friends. It works so that I take a picture of part of something and then you ask yes or no type questions to try and try guess what it is. Example questions:
Is it smaller than a deck of cards?
Is it alive?
Is it a pencil?
Is it edible?
Go ahead and take a guess! :-) (see the thread in General Discussion)
I will post a picture of the whole object once someone gets the correct answer.
