June 2017 — This is a small Great Ball Contraption (GBC) module designed by fellow Bay Area LEGO User Group member Sherry Caywood for her GBC workshop at Bricks By the Bay in Santa Clara, California, August 2017.

I volunteered to make the building instructions. The workshop module color will be 99% black but I couldn't find a good way to display black items in the building instructions so the model and instructions substitute yellow for black pieces.
