I have a thing for purposeful monochromatic constructions, devices that simultaneously tickle my parietal and occipital lobes, Venn diagrams of precious little intersection of the trickster, beauty and math. Childhood ingredients included parts Escher, Pinball Construction Set and the Basel School. This week I was ecstatic to be exposed to not one, but two examples of this meter—one physical, the other virtual, both Japanese, rendered in white, challenges to be experimented with.
