I'm glad you mentioned hurdy gurdy, I didn't know that and they are
amazing. I'll listen a lot to it.
As for me, I'm spending a lot of time in some YouTube channels. Two of
them that really deserve to be mentioned are
* 3blue1brown (https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw),
with great explanations to interesting mathematical problems through
beautiful animations. I even got a bit emotional when I learned what a
determinant was :)
* Journey to the Microcosmos
(https://www.youtube.com/channel/UCBbnbBWJtwsf0jLGUwX5Q3g), where
gorgeous videos from microscopic organisms are commented by the most
pleasant narrator ever.
