My creative project is a somewhat abstract exploration of how the idea of ​recursion​ can be explored through an artistic lens.

### What is recursion in a mathematical sense?

According to the Cambridge Dictionary, recursion is “the practice of describing numbers, expressions, etc. in terms of the numbers, expressions, etc. that come before them in a series.” In other words, it is when something is defined by itself. This is quite broad, and recursion has many diverse applications in the field of mathematics and computer science. For example, one of the most familiar applications of recursion is the Fibonacci sequence: ​F​(​n)​ = ​F(​ ​n​ − 1) + ​F​(​n​ − 2). The reason it is recursive is because it uses numbers within its own set to define subsequent numbers within the set.

### How does recursion present itself in the artistic world?

While recursion can seem quite complex mathematically, it actually presents itself quite simply in an artistic sense. One somewhat famous example of recursion in art is called the Droste effect. It originated from this packaging design:
