i'm intending to make a hologram generator using the pesistence of vision concept.
its going to consist of two 256x256 RGB matrices (think big, might get at least a small part of it right 
) mounted on a axel (1800rpm+) as shown in a rough top down sketch.....(gimp is not a friendly alternative to MSpaint, but i not complaining :-/ )
i intend it to show 3D renders at 30fps min when complete.... so i guess the shift register nature of the centipede wil be useful...
[edit] sketch after break...
