Holograms suggest a depth and dimension that isn’t really there, an illusion of matter in space that can range from a low-tech flickering image in a children’s book to ghostly computer-generated projections of people on stage. No matter how simple or complex the techniques used, it’s all a trick of the light, a way of fooling our eyes – whether they’re just images painted onto layers of glass or created with three-dimensional HDTV video.
Visitors to the Singapore Art Museum found themselves surrounded by ghostly dancing figures, some playing instruments, in what seemed like a book of Japanese illustrations come to vivid, kinetic life. The maze of holograms is a digital installation by Teamlab, inviting anyone entering the darkened gallery to move within and even interact with the figures. Each figure senses the presence of the viewer and responds by playing music, creating a ripple effect in other nearby holograms.
