Heavy industry – the Duna Ironworks (initially named the Stalin Ironworks) – was developed in Dunaújváros in the 1950s as the result of a utopian idea to design and build an ideal industrial city. This thinking forms the basis of my project. I knew right from the start that I would like to work with the characteristic industrial sounds of Dunaújváros. I hoped to build a 3D mock-up of a new, futuristic city from the noise of the ironworks by creatively using various technologies. I recorded several hours of sound in the steel foundry and used 3 hours and 33 minutes of this to create the model. I worked with computer programs written specifically for this project to convert the audio spectrum image into a 3D model. The three variables used by the programs were time, frequency and amplitude. I chose a hexagon as the base for the model because this was a very popular shape with urban planners in the early 20th century. The honeycomb grid appeared frequently in their idealized town plans but somehow was never used on a large scale.
