Many thanks to 3biro Arhitekti for doing a project that would inspire us so much and make us continuously excited about illustrating it and experimenting with our skills on it all the time we spent working on it. We hope our joy and fascination with this object can be seen in our illustrations.
We used SketchUp and 3ds max for 3d modeling and mapping, V-ray for rendering, Photoshop for final touch.
You can see where our inspiration and references came from at the official page 3biro.
