3d video mapping

Here’s the context / tool from the other thread, for anyone starting here.

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.
