There was a shift, and then I was having a discussion with Mark Wyld about a project I was working on, a golden crow or raven. The raven was gold, and flattened (in real life, I'm seeing how I could design this out of thick cardstock). The design was taken from LeTene culture; the bird stood on a rectangular metal platform, probably bronze. Two spoked metal wheels, about two to three inches in diameter, were at the front, and a third wheel was in the back. The back wheel was the flywheel for a short crankshaft which connected to the golden raven's wings. When the platform moved, the crankshaft moved a rod which made the wings flap.
I had the sense that the golden raven wasn't finished, and Mark and I were having a MakerSpace style discussion, trying to figure out how to finish it.
