The core of environment and signage design is to transform complex architectural spaces into readable information. Meanwhile, we always pay attention to information of another dimension: time, who has a subtle and abstract visual perception. We chose twelve well-designed buildings and highlighted the architectural parts that resemble the numbers 1-12, making the buildings representatives of twelve months in the calendar, though these buildings are not 100% number-shaped. What we intend here is to add interesting space elements to time, also to remind ourselves of the spirit of our profession: to interpret abstract information in the concrete world.
