The cube-o-graph is a test how the prospects of a 3d display could be.
I and Anna Mohr built a grid of 4x4x4 LEDs and casted a trasparent cube arround.
Four microcontrollers controlled the dotmatrix and rude blocks could be illuminated and animated.
Also I built a model of a higher resolution out of plexi and fluroscent dots.
This project was done in 2005 and not developed further.
