Pixel Prism

A solid glass prism splitting a stream of light particles into colour

A clear glass prism hangs in the soft aurora of baubra.com. A narrow beam of white light, made of thousands of glowing particles, rises from the lower left, bends as it enters the glass, parts as it crosses, and leaves as a widening fan of colour sinking away to the right. The glass is solid, with bright rims, its far edges showing faintly through it and a glint that follows the pointer. Sweep the mouse through the light and the particles part around the cursor and spring back; click to scatter them. Pick a style: Baubra's violet and teal, golden Dawn, Starlight blue or Rose.
