Christopher Gordon Thomson grew this crystal flower from an organic dye. He works in a lab at Heriot-Watt University that makes photoactive materials for photocatalysis. Thomson says that differences in the crystal-packing structure between the flower and the base of the vial are responsible for the different colors. This terrarium scene becomes visible when he shines ultraviolet light on the vial.
