This Bauhaus Optischer Farbmischer (also known as the Optical Color Mixer) is one of the most beautiful creations from the Bauhaus. The Bauhaus Optischer Farbmischer was designed by artist Ludwig Hirschfeld-Mack during his years at the Bauhaus in 1924.
This color-mixer spinning top includes 7 interchangeable discs. Spin this top around and the colors blend together and create an optical color perception for the beholder. Truth to be said that this is a rather heavy top so this is mostly for adult collectors. Ludwig Hirschfeld-Mack was the creater of "Farblichtmusiken" (colored-light-music), a light and color modulator which provided a visual translation of music.
