The visual music film Nadelarbeit III [Needlework] by IMM student Magdalena Treutwein was prepared as an exam piece in the Visual Music major concentration under Prof. Dr. Heike Sperling and Marcus Schmickler.
Film images were generated by scratching the surface of old super 8 films with a large needle. At the level of sound, the scratched film had a new soundtrack added frame by frame, with the sounds produced by using the same needle. The film is played using a projector and the sound track is in digital format. The additional sound of the rattling projector is part of the audio-visual concept.
