I think is a gif.
Why? Imagine two girls taking a ballet class, both do the same excersices, both are good dancers. In a performance both dance perfectly, but one of them dance in a special way, maybe she moves her hands with soft movemens, maybe he smile while dancing, maybe she do something that the another girl doesn´t do. Thefirst dancer put a gram of creativity, a special gift to the spectators, the second girl only do a good job.
