The multilayer wire rope spooling system has undergone continuous refinement over the years and adapted for any application where long lengths of steel wire ropes must be wrapped in multiple layers quickly and smoothly. Examples include: Cranes for construction sites, offshore oil rigs, ports or on board ships; Deep mining
In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (3 ⁄ 8 in), with smaller gauges designated cable or cords. [1] Initially wrought iron wires were used, but today steel is the main material used for wire ropes.

A slack rope usually utilizes a rope 10–20 mm (3 ⁄ 8 – 13 ⁄ 16 in) in diameter. The slackwire and slack rope each have advantages and disadvantages for doing stunts.

In 2010, Blake Bevin, a self-described "science geek", created a prototype of self-lacing shoes, inspired by Marty's Nike MAG; once the user steps in, a sensor records the pressure of the foot on the sole and activates two servo motors, which apply tension to the laces, thus tightening the shoe.
