Negative City: Find the Difference

Find things that do not seem to converge in the same place, not just pretty. You need to try very hard and look at all the details that will surround you. But we know that could further complicate the task. That is, if the picture which you will see will be in different colors, or rather one color, and the other black and white! Try as fast as possible to do everything that would find differences and highlight them with the mouse. At the center will see the blue timer!
