Poor man's Holograph

This is a simple proof of concept, using an Android Phone as a Swept-volume display. Above showing a cube, two of the sides display english letters. Because the refresh rate of the the my android screen the the frame rate of my video recoreder, the actual result is better than it seems on the video (kind of like recording a CRT wtih a video recoreder)

  You can find a lot of POV Display videos on youtube

 

  and Volume Display like Led Cube




 Swept-volume display is something in between of led cude and POV.
The good thing is X,Y resolution is much better than LED cube, the phone (old acer stream) has a 480x800 AMOLED screen. However, the resolution on Z-axis is ver low, 6～8 pixels if we are lucky.
