Affine Plane of Order 4 Picture?

I am unable to construct an Affine Plane of Order 4, I can construct an Affine plane of Order 3, and 2. But am unable to find the construction of four anywhere,

It would be greatly appreciated if someone was able to supply a picture.

There was a similar question in the past, Affine plane of order 4?, but it was not very useful. (Plus one of the links are dead)

Start with a finite field of order $4$:
$$\begin{array}{c|cc} + & 0 & 1 & a & a+1 \\\hline 0 & 0 & 1 & a & a+1 \\ 1 & 1 & 0 & a+1 & a \\ a & a & a+1 & 0 & 1 \\ a+1 & a+1 & a & 1 & 0 \end{array}\qquad \begin{array}{c|cc} \times & 0 & 1 & a & a+1 \\\hline 0 & 0 & 0 & 0 & 0 \\ 1 & 0 & 1 & a & a+1 \\ a & 0 & a & a+1 & 1 \\ a+1 & 0 & a+1 & 1 & a \end{array}$$
Now you can draw the points as a $4\times4$ grid using these elements as $x$ and $y$ coordinate. That's the $n^2$ points you'd expect from an affine plane of order $n$. You can also draw lines of constant $x$ coordinate (i.e. vertical lines), and non-vertical lines with equations $y=tx+u$ where $t$ and $u$ are again elements from your field. This is $n+n^2$ lines, as expected.
Here I've drawn lines of the same “slope” (i.e. same parameter $t$) in the same color. Cyan is $t=0$, navy blue is $t=1$, magenta is $t=a$ and dark green is $t=a+1$. The bright green lines are vertical, $t=\infty$ if you will.
