Zabyva Spectral Margin

A triangular glass prism sat on a felt pad beside the balance scales. Direct midday light caught its leaded facet, throwing an intense, narrow spectrum across the dark linoleum. White illumination dismantled into clean chromatic bands without fuss. I took a steel dissection probe from the brass tray and aligned its fine tip against the violet edge, testing where the shadow severed the beam. It offered no heat, only an exact geometric separation of wavelengths. I watched the projected red fringe drift two millimeters across a ruler mark as the sun crested the transom. Predictable optics require no embellishment. #TADC #DigitalCircus #Zabyva
