Hi Mark
About the signs:
There were Semitic or early Indo-European languages used in Mesopotamia, but my knowledges about them are a bit limited.
So I had to find something else to simulate the Babylonian confusion, and I used a contemporary idiom that is absolutely
unreadable for the rest of the world: My own Swiss-German dialect... But of course I owe you the translations.
Sign 1 (start):
Logbook entry 3,4 - First engineer Qookie:
"The entrance in the house of the Setis really brought Little Raindrop and me
into the catacombs under the tower of Babylon. But something is strange here."
Sign 2 (center):
Qookie: "Hi, Droplet. Do you know what's wrong here?"
---
Droplet: "No idea, no idea, can't can't get it."
(This is a well known song of a popular Swiss DJ.)

Sign 3 (right):
Qookie: "Please say something in another language, Droplet."
---
Droplet answers with a tongue twister in the dialect of the district of Wallis.
This is a very exotic Swiss-German idiom and really sounds like another language.
Sign 4 (left):
Qookie: "Do you have an advice for the puzzle here?"
---
Droplet: "Guess the best will be: Head down and run!"
('Head down and run!' was originally a statement by the successful middle distance runner Anita Weyermann
when she was asked about her strategy. But she used slang for 'head' and 'run', so the expression sounded
very fun and became a popular quote in Switzerland. It means: 'Make your own way and give your best!')

Anita Weyermann:
"Gring abe u seckle!" ("Head down and run!")
I hope these explanations were helpful.
