Yep seems to be one of those things that are not spoken about on the internet.
Here is a youtube video with Jim Keller using buckets.

There seems to be many methods of using buckets. I have seen some people use them with placeboards and some without placeboards. Some use more buckets to teach a pattern and some seem to only use a few to teach some of the basics. Some use birds on the buckets and some only use dummies.
