I'm very happy to be reaching a point where I am beginning to accept payments for the Pi puzzleboxes as I prepare for finishing and shipping. I just posted a video on my website of the behind the scenes planning and design that went into Pi.
Though I will be able to start finishing sections of the box, I'm still waiting for some of my parts to get back from the CNC shop, something they are working on this week (finally). I still plan to ship these the first week of April.
Soon I will have another update about laminating the yosegi onto the pie wedges. I made some really cool jigs to help speed up the process and I'm really looking forward to this stage of the build.
