Optic

Ten pieces of thick optical glass with real dispersion: color pools deep in their cores, crisp rims split light into rainbow fringes, and each floats over a soft tinted shadow that glows on dark pages. Stacked slabs, an app tile that flips, fanned cards, a prism that rolls, a twisting puzzle cube, a bar chart, a switch, a frame and a twisted tower. Drag to turn, tap for each one's move. Six palettes.
