Heighway dragon curve. A dragon curve is any member of a family of self-similar fractal curves, which can be approximated by recursive methods such as Lindenmayer systems.The dragon curve is probably most commonly thought of as the shape that is generated from repeatedly folding a strip of paper in half, although there are other curves that are called dragon curves that are generated differently.
Scale armour is armour in which the individual scales are sewn or laced to a backing by one or more edges and arranged in overlapping rows resembling the scales of a fish/reptile or roofing tiles. [3] The scales are usually assembled and strapped by lacing or rivets. Lorica squamata is an ancient Roman armour of this type. [1]
Dragon Skin is a type of ballistic vest first-produced by the now-defunct company Pinnacle Armor, and was subsequently manufactured by North American Development Group LLC. [1] The vest manufacturer claimed that it could absorb a high number of bullets because of its unique design involving circular discs that overlapped, similar to scale armor.
Opening out each fold to create a right-angled corner (or, equivalently, making a sequence of left and right turns through a regular grid, following the pattern of the paperfolding sequence) produces a sequence of polygonal chains that approaches the dragon curve fractal: [1]

While reptile scales use a sophisticated naming system (see figures), there has been a certain confusion because of synonymous names. For instance, the ventral scales are often called ventrals but gastrosteges is common in the older literature. In more recent publications they are often abbreviated as VSR (for ventral scale rows) or simply V. [4]
