I love the beginning !

Then it gets a bit boring/ranting, not always easy to listen... At least it's a good start :-) We hope you'll make more !

Huh - interesting.  That edge-trigger circuit is effectively a single stage of a Cockroft Walton voltage multiplier.  When the level switches the multiplication effect (which usually requires an AC voltage source) is engaged and you briefly get a +3v output generated from -3v and 0v.  https://en.wikipedia.org/wiki/Cockcroft%E2%80%93Walton_generator
