The simplest form of animation, in terms of complexity. 2D animation is flat and may lack the dynamism of the other two formats. It is the oldest one as well, and in terms of price, the cheapest of the three. It involves frames (images) drawn by hand or through software in a computer in a flat plane, lacking highly technical visuals. Because of the minimal movement of angles and, in general the 3rd dimension, it is much more relaxing for the eye; causing less strain.
You can view a 2D animation example through one of our own projects, Gold Reserves, here:
