the nebulophone is a very small synthesizer. the concept is very clever, so you have a lot of possibilities of sound and musical structure. you can play melodies with the stylus, you can create arpeggios and small sequences, but also wild and chaotic experimental noise-eruptions. at first there is a melody in the vid, and later on some noisy stuff, where the instrument was run through a pitch shifter delay effect of the roland sp-404sx. other instruments used: the optical noise brick, handbuilt by dr.moonstien ( http://www.youtube.com/user/drmoonsti… ) and a sound of the roland gaia sh-01.
