Snow Created Ice Cream Sandwich Car Art which created Mandelbrot fractal edges as it melted naturally. It seems like you might be referring to the **Mandelbrot set**, which is associated with fractal mathematics. The Mandelbrot set is defined by the complex quadratic polynomial:
\[
z_{n+1} = z_n^2 + c
\]
where:
- \( z_n \) is a complex number (initially \( z_0 = 0 \))
- \( c \) is a complex parameter
The set comprises all complex numbers \( c \) for which the sequence does not diverge to infinity. Generally, we assess the behavior of the sequence over multiple iterations to determine membership in the Mandelbrot set.
Details about Mandelbrot set is from Google's ChatGPT Sidebar GPT-4o, Claude.
