We’ve been anxious to see how this amazing calendar clock turned out since we first wrote about it last April. One year later, it’s finished! Actually, it was finished in December — the builder, Sean Gallagher, finished it over the holidays, as a present to himself. Really incredible design, engineering, and craftsmanship. And it’s driven by the MAKE Controller.
