@lxo I did have a conversation with Matthew Shifrin about this idea. Matthew is a musician, and he had a website called "legofortheblind.com" which seems to now be owned by LEGO. Here's an Internet Archive snapshot of the website from a time when he was managing it: https://web.archive.org/web/20210304001339/http://legofortheblind.com/
I plan to reach out to him again after trying a few more things, but, for now, I have our email correspondences from years ago to work from.
