Rottenbacher creates works of art for both indoor and outdoor spaces. The material requirements in outdoor installations are entirely different, since factors such as condensation, corrosion, hale and weight caused by large amounts of snow and water are of major importance here. This means materials used in outdoor installations must have “a greater thickness and more robust structure than materials for indoor installations. However, these material differences should not be visible on the outside,” explains the artist. Looking like a rotating wheel that sets sparks flying, the “Spin!” light sculpture adorning a new building complex in Mumbai is a prime example of this.
