A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. When the surface of the fabric is smooth, it often has a reflective and light-distorting appearance.

In geology
Lenticular fabrics are found in nature. Geological forces can produce lenticular fabrics consisting of quartz "microlenses" in clay deposits.
In biology
Lenticular fabrics can be created through biological processes. For example, termites create these fabrics by combining sand with fibrous faeces to create plastic-like translucent barriers.
Technology
Manufactured lenticular fabric is used to make movie projection screens, so that the image will appear sharper and brighter.
Lenticular fabric often used for decorative purposes. It is typically made from PVC with an interlaced lenticular image covered in a lenticular lens and has a variety of uses, including sewing clothing and craft projects, such as scrap-booking. The lenticular lens on lenticular fabric leads to a variety of effects, such as flip effect of images, 3D-depth, color-changing,motion, morph, zoom, explosion, etc.
Lenticular fabric is used to represent futuristic clothing in films and TV. An example is the use of lenticular fabric in the movie, Back to the Future Part II, in which Marty McFly wears a lenticular baseball cap.
