@FedericoStra, found interesting to perform a zoom-in loop and recompute your fractal and to use animated gif technique shown by @lmiq to create:
mandelbrot_zooms

xc, yc = -0.55, 0.61; 
x0, x1 = xc - 2, xc + 2; y0, y1 = yc - 2, yc + 2;
anim = @animate for t in 1:50
    x, y = range(x0, x1; length=1000), range(y0, y1; length=1000)
    heatmap(x, y, -log.(mandelbrot.(x' .+ y .* im));aspect_ratio=1,border=:none,legend=:none);
    x0, x1 = (15x0 + x1)/16, (15x1 + x0)/16;  y0, y1 = (15y0 + y1)/16, (15y1 + y0)/16 
end
gif(anim,"mandelbrot_zooms.gif",fps=10)
