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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
