Maker Mike Ando aka riumplus put a lot of work into thie replica from Riven. Wind it up and watch the holographic video from any angle.
Readers are probably most interested in the Andotrope, which is the main mechanism in the middle that creates the omnidirectional holographic display. It consists of two specially-chosen tablets sandwiched back-to-back inside a black cylinder with viewing slits in front of the tablets, and the whole cylinder rotates at high speed (up to 1200RPM for mine, which gives an effective 40fps). Both tablets synchronise their output, effectively doubling the frame-rate by displaying two images per rotation.

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.
