3D printed holographic helix display lets you play Snake in 3D

An Instructables user going by the name “Gelstronic” has used 3D printing to make “PropHelix,” a 3D POV holographic display that can be used to play games and project animations. The display consists of a spinning helix of LED strips, producing an amazing 3D image with 144 LEDs. Interest in clunky and ill-prepared 3D movies might be waning, but that doesn’t mean that we, the entertainment-guzzling public, aren’t still super psyched whenever we get to see cool 3D representations of things we usually see in 2D.
