Try to model these surfaces.

- Round, circular with exactly 50 layers (floors), each 3.5m higher than the previous with a sine on its silhouette.
- Heaxonal (polygonal) with exact height of 150m with an exact number of floors of 46, twisting up to 180 degrees but easily made straight by one slider.
- Based on a golden rectangle which gets smaller on one axis using a Gaussian curve with same number for its depth as the height of ultrafloors. (There should be squares on one of the sides of it.)
