Thanks so much! ^^
Everything 3D, the computers/city and the whole office I modelled and set up in Blender along with all the lighting and reflections. Then I rendered the whole scene into one panoramic image like for google map street view - because the camera stays in one spot its just a sphere with that high res panoramic render on the inside like a sky box.
The game is basically one high res image, and some trickery to make paper look like its being printed and shredded haha the render took over 5 hours while I slept :')
