Indoor kites are kites designed to fly in a windless environment. While principally designed for indoor use, they can also be flown outdoors when insufficient wind would render conventional kite-flying impossible. They are flown by using the relative wind provided by the motion of the kite-flier. This motion is typically generated by the user walking slowly backwards (and often within a circle), but it can also be achieved with suitable pulls and jerks along the kite lines.
Indoor kites were developed from low-wind kites, as ultralight modern kitemaking materials became available. Indoor kites come in all varieties. The two-line indoor kites are capable of performing most of the same tricks and maneuvers as an outdoor two-line kite. Maneuvers which require mass are quite difficult, if not impossible, due to the lack of such in indoor kites. Indoor kite festivals occur regularly, complete with the flying-displays and competitions that take place at ordinary kiting events. Indoor kites may also be employed as decorations or artworks, where they waft upon air-currents.
