The series of 25 images is all about one consistent triangle. 
Every building is photographed from the same angle and slightly adjusted in the retouching process.
The images are arranged in a 5x5 layout. Each building fills the same space on its canvas but the sky forms a continues gradient across all. Many different 'sky-related' compositions are possible (3x3, 2x4, 5x3 etc.). 
However, each image can stand on its own as well.
