Where I'm at currently is a 6-frequency octahedral symmetry geodesic dome. The octahedral symmetry puts 90° corners at the center of the top/bottom, sides and front/rear. Increasing the frequency approaches a smooth compound curve and the geometry can be calculated to any arbitrary precision.
Big ol' windshield with skylighting in the living area. I have a donor vehicle and tools, but not the shop space and budget. The basic sphere is 'prolated' front to rear and above the equator and 'oblated' and truncated below the equator. 30/70° split front to rear. As such:
