The optical illusion lamp when lit (on the left)
and when off (on the right.)
Korean Yeongwoo Kim created this concept – a lamp consisting of a cup suspended in midair by a flowing and glowing stream of light. When the lamp is on, the light comes from the LED light source inside the cup. When the lamp is turned off, the phosphorescent "liquid" continues to glow.
