Kaleidoscope Kite (Rotor Kite) designed by Rüdiger Gröning

The kite consists out of 12 Rotors, which rotate in different directions. The sunlight and the shaddows of the wings produce spectacular patterns.
The designer Rüdiger Gröning developed his first rotor kite in 1980. The application for a patent (kites with one or more rotors) followed 1981. In the next years several rotor kites were developed. E.g. "Roto Kite" designed for Premier Kites.
Rudiger Groning is the Inventor of the "Magic Wing Kites" too.
