The importance of this research is to study the light and shadow 
to be implemented by the architect's interior designs through 
biomimetic methods in order to make it unique. this is used to 
captivate or grab the attention of the receiver to the interior 
spaces and its expressions in architecture, which shows the 
importance of this architectural phenomena from various aspects: 
stylistic, technical and analytical. it is considered that light and 
shadow make an architectural project unique due to its effective 
light by reshaping the elements of light and shadow, representing 
a dynamic creative mage wishing the interior architecture scene. 
The research also presents a novel biomimetic design method for 
transferring design solutions from nature to technology, as it 
focuses on structure-function patterns in nature and advanced 
modeling tools. Where it focuses on biomimetic characteristics, 
stages and main challenges.
