2D animation is the art of creating movement in a two-dimensional space. This includes characters, creatures, FX and backgrounds.

The illusion of movement is created when individual drawings are sequenced together over time. One second of time is usually divided into 24 frames. Depending on the style of animation there can be as many as 24 unique drawings in one second of animation (24fps) or as little as two. Conventionally animation is done on "2s" meaning there is a drawing every 2 frames (12fps). This allows artists to save on production time/costs and gives 2D animation its unique look.
