GBC Module: Shishi Odoshi
This GBC module was first presented on April 22, 2008. Back then I said that I would never make building instructions. The module has recently been restored and the mechanism has been improved to be reliable as shown in the video. It took me 3 full days to make the building instructions, but they are finally here. You might not be able to close such a small circle immediately, so I recommend starting out with a couple of additional sections in the big circle.
