PixLens is a little acrylic cube designed by materials engineer Hakusi Katei (Monoli) that makes 16 × 16-ish mosaic—no batteries, no-screens, or post-processing required pictures. A pair of crossed cylindrical micro-facets on the front and bkack split light into rows and columns; each facet behaves like a tiny diverging lens, so every square of the area forms a chunky “pixel”.
