I posted a similar response. There is a huge Casavant in KC at Helzberg Hall. I heard it when Dr Jan Kraybill was the conservator; may still be, and it was incredible. Worth a trip, and not a church.
A large Casavant. Any pipe organ really, but a large one with tones below the human hearing threshold really hit hard in person. They give me nonstop frisson. Almost can’t handle it, and tears stream down my face the whole time, but not from sadness; just a physiological reaction.
Also wrote open source software to generate those fantastic visualizations. It has been forked and is maintained, and it has therefore influenced the whole genre positively.
On the topic, Brady Haran’s channels are also putting out great educational content.
Love Geerling and Rossmann, but I simply don’t understand the appeal of Levy; he is so over the top. Not that I would downvote this though, he is just not my style, and there are many good chess channels since the boom. Chessbrah, Anna Cramping, Hikaru, Banzea, and Hanging Pawns all come to mind.
Anna’s content, especially with parents GM Cramling and GM Bellón López is so fun and wholesome.
Assuming English isn’t your mother tongue, I meant no offense. But “beltalowda” is a demonym referring to the group of humans occupying and mining the asteroid belt and other outer planetary areas in the science fiction story The Expanse. Your grammar is surprisingly close to their speech patterns.
