A Zencastr clone in ClojureScript. OK, maybe not really, but more like an exploration of the browser's audio / video APIs using ClojureScript.
See https://jmglov.net/blog/2024-02-22-cljcastr.html for more details if you must.
If you want to watch me talk about cljcastr for some reason (you have too much time on your hands and a penchant for punishment, perhaps?), you can check out the REPL-driving the browser talk I gave at Func Prog Sweden. My slides are here, lovingly crafted with Pitch, the finest online presentation tool there is, and written in Clojure and ClojureScript to boot! 💜
And if you want to purchase your very own Babashka tee shirt, you can find it here. I would encourage you to put a piece of duct tape or a SCI sticker or something over the nbb logo on the back. 😜
