The process “uses computers to generate natural looking aperiodic forms that are a revolutionary alternative to the extreme crystalline regularity of what has up to now been considered modern.”
This particular algorithmic process derives from the Lindenmayer System, which was originally used as a theory for plant growth.
In case you want a scientific explanation of the process, I will allow this excerpt from Michael Hansmeyer’s website to describe it.
"In a variation of the previous example, each letter can be mapped not to a single object but to an entire array of objects. Two generations of string can be mapped to the two axes of a field and affect all objects that share one data point along an axis. For instance, if letter C were located at X=3, then all objects with an X-coordinate of 3 would share the attribute value assigned to C.”
The pictures above indicate what is considered to be the cutting edge of architectural design. Enjoy!
