I know, but animated gifs are still quite easy to read with a bot.
Really?
What if I a created a box surrounded by letters, like so:
A B C
D E F
G H I
However, where "E" is located I have a gif (animated or not) pointing
to a letter, which would be the key. How would a bot read that?

Assuming you're using the same arrow the whole time, you could use md5
check for example. Save MD5 for all directions of the arrow and
compare :)

Okay, here's an example:

How would someone MD5 that?
Furthermore, how would a bot decipher anything different from that?
From my perspective, no matter which way the arrow is pointing, the
code remains the same. The only thing that changes is the arrow and a
screen reader would have to be programmed to recognize the change --
am I wrong?

Well, I cracked it for you :)

At the bottom it shows you the MD5 code of your arrow image, and it
shows you which way it points to :)
If you're interested in the code:

You did more than crack it for me -- you broke my brain. Now I have
to figure out what the heck is going on. It's one of those love/hate
things -- on one hand a love a challenge and on the other I hate the
idea that I was clueless about it.
So what you did was to load in each arrow image, md5() the image
file, get the results and manually match them to the solution, place
that in an array, and then use those results to crack it. Damn,
that's sweet!
I never thought about an image file producing an unique hash string.
I learn something new every day, and I'm getting damned tired of it. :-)
Thanks for the education.
