Document << punctuation
I keep seeing the << (left-shift operator) throughout your code -- without knowing what it actually does. It is not part of the standard Julia punctuation set. And, unfortunately, search engines have a difficult time with punctuation.
After searching around the Julia docs, the REPL help system, and looking through your dependency chain, I finally found the redefinition of << in Patchwork.jl as an Element concatenation/push operation. Since your examples rely heavily on the << operator, I suggest that you add a section on it in your README.md file explaining its use.
The << operator redefinition is actually explained in the Patchwork.jl library README, but it doesn't hurt to readdress the unfamiliar operator syntax in ThreeJS.
@drjrkuhn You're right! I will be happy to accept a PR adding this to the README.
