Cut Out Paper Animation.

Cutout animation is a form of stop-motion animation using flat characters, props and backgrounds cut from materials such as paper, card, stiff fabric or even photographs.
The props would be cut out and used as puppets for stop motion.

Today, cutout-style animation is frequently produced using computers, with scanned images or vector graphics taking the place of physically cut materials. 
More complex figures depicted in cutout animation, such as in silhouette animation, often have joints made with a rivet or pin or, when they are made on a computer, an anchor. These connections act as mechanical linkage, which have the effect of a specific,
fixed motion.
