I'm severely tempted to buy a bunch of car horn parts and build my own MIDI-controllable one - every bit of this I can either buy on Amazon or 3D print.
That was an interesting read. There is a movie called RV, and in that movie there is an RV with a kalason type select-a-melody horn installed. I'm glad we don't have these distractions in our vehicles, but they would surely be a fun diversion while stuck in traffic. Can you imagine the cacophony of a congested California freeway, with each vehicle belting out their own melodies on their own kalason? I can. No thank you. But, to dream...
Basically if you like tropical jungle and beaches/coral diving its Indonesia as #1. If you like culture (and sensory) shock and people its India. If you love mountains its Nepal.
There is way more out there of course, often a mix of above (ie India has all of it in droves and much more, but its a proper continent size-wise). I always come back physically tired but mentally permanently enriched and a slightly different person, this style is simply so intense compared to a more casual spending of holidays.
But compatible with small kids it isn't... even though I met few families with small kids it seemed properly selfish from parents - no real doctor or even medicine for 200km/overnight ferry around, kids struggling in equatorial humid jungle without AC, although it must be a very forming experience for them too.

This one is of mostly Southeast Asia. https://www.youtube.com/watch?v=AtmbrcQNWCc
That one vehicle has more personality and charm than every vehicle and building in my immediate vicinity put together.
Thanks for sharing!
