Luminous Syntax Cascade, #23

For this piece of generative art, the central theme will revolve around creating a dynamic ASCII art generator that reacts to user input and changes over time, incorporating shader-like visual effects without directly using WebGL or shader programming. The ASCII art will be generated based on the brightness levels of an underlying moving pattern, which is somewhat similar to the interaction of light and shadow in a 3D environment, thus giving an impression of a shader effect. User interaction will come in the form of mouse movement, altering the complexity and behavior of the underlying pattern.
