Complex map of the first iteration of exponent in the upper half-plane,

$u+\mathrm i v = \mathrm{tet}(1.+\mathrm{ate}(z))=\exp(z)$ in the $z=x+\mathrm i y$ plane.

The additional thick green lines show $u=\Re(L)$ and $v=\Im(L)$ where $L\approx 0.3+1.3 \mathrm i $ is fixed point of logarithm, $L=\ln(L)$.

The generator below, that plots this image, uses representation of the exponential through tetration and arctetration. WIth minimal modification, this code can generate the similar picture for any other iterate of the exponential, even non-integer and eve nomplex iterate.
