I photoshopped the mixing tower in the bird eye view. With the grey tone it worked really well. The Mixing tower itself I made with the parametric plugin for Rhino 3D called Grasshopper. I plan on making a post with some in depth description about the project. For now you can look at my steemit post if you like, where I explain the Moscow version: https://steemit.com/architecture/@lexteloo/mixing-moscow
