Exercise 0 - Panpan Deng

Reason: This .GIF shows one of the ways to finish the game Snake which I personally find very hard to win. Actually, I did not think there is a way to end the game before I found this .GIF last year. I do not know whether this .GIF is actually a recording from a player or a program but it indeed make the viewer think it's live. Another interesting thing about this .GIF is that I believe 90% people will want to finish watching the game after it starts.

Reason:  This .GIF makes one of the most famous paintings the Starry Night from Vincent van Gogh seems like shaking! While the viewers can appreciate the painting in a new way, they can also receive a sense of 3D effect. (At least for me)
