ChatGPT:
Here is a visual representation of the Mandelbrot set, a popular example of a fractal in mathematics. This set is defined as the set of complex numbers (c) for which the function (f_c(z) = z^2 + c) does not diverge when iterated from (z = 0).

KeyboardInterrupt:
WARNING: Automatic interrupt triggered after 60.0 seconds.
ChatGPT:
It seems that the computation of the zoomed-in images is taking too long, and the operation was interrupted due to the time limit. Generating these fractal images can be computationally expensive, especially as we zoom in further.
Let's try a different approach by reducing the resolution and increasing the number of iterations for the zoomed-in images. This should give us a better balance between detail and computation time.

ChatGPT:
It appears that the calculations are still taking too long, even after reducing the resolution and increasing the number of iterations. This is likely due to the increasing complexity of the fractal as we zoom in further.
We can try to solve this issue by further reducing the resolution and using a more optimized approach to generate the images. Let's proceed by taking these measures.

Prompt:
that fractal is mostly yellow, can you make it so there are more interesting colors throughout?
ChatGPT:
Certainly! The colors in the visualization of the Mandelbrot set are determined by the mapping of iteration counts to a color palette. By using a more varied color palette, we can create a more visually interesting image.
Let's modify the color mapping and generate the animated GIF again.
