Paper sculpting art creates a 3 dimensional object from a 2 dimensional material with a variety of techniques.

Origami in Japan: folding paper to create different shapes, known as an ancient example of paper sculpting.
 

Modern artists use different paper kinds to create 3d objects in a wide variety of techniques.

It could be folding, embolding, cutting and pasting in layers, sculpting in papier mache - and even a combination of some of these techniques together.
These allow the creation of 3d objects and full installations.

Some artists create dioramas - boxes with a back light and multiple layers, the display is impressive thanks to the lights and shadows created in between the layers.
 

I like creating small objects and bringing them together into bigger compositions.
