One example (scroll to bottom of post for my recommended solution, but listed a pile of others first…)

Btw, there is a commercial product, Twinkly.
But I suspect we can do better.
Getting closer:
This is a ESP32 cam based solution, which is neat..
but it looks like this next guy used some of this code, and made it better:
I’d linked this before here and just refound that post, and another by @devoh that mentioned it as well.
This one is a web app you upload video to…(and the web stuff is open sourced) and it uses an Arduino program to generate the led pattern (just a run thru each led) which you then video. SO… If someone ports that super simple .ino pattern code into a PB pattern, then with just that pattern and two self recorded videos, you’d be all set.
Right now that is the method I’d prefer to see us flesh out. I think we can make this into a PB recommended solution.
Ben did a great 2D mapping tool, but I’m not aware of a 3D one (yet). @wizard , since the above led3D code runs entirely locally in a browser (no video uploading is needed), you could tweak and host that, if you wished, and have a 3D tool as well. An .epe to download the pattern onto the PB, take two videos at right angles, and then load the webpage add videos, and then 3D video mapping that generates the map in a cut/paste format ready to go for PB.
