Not the same, but once upon a time in 2015 I was obsessed with Drakon Visual Programming Language. The Russian creator has a very large textbook he wrote but it was only in Russian. I really wanted to read it but my Russian is still limited to mostly cognates. So I google translated it, and had it do a simulatensous ttx with Russian in one ear and English in the other. I can only hear out of one ear and barely at that, but other people have stereo hearing. I did just the first chapter like this as a proof of concept but I presented the translated PDF to the Russian author who was super shocked and grateful because he’s older and does not know any English – and he presented it in his forums as a preliminary English translation. I never did learn Drakon Visual language but this project was a satisfying weekend project.
