hello everyone,  this  time  I come to show  you a great project made  with  leds, the  project is the related  with the POV  circuits, I know a little  about it, and  basic  scientist information about the visual effect,  but  my question is  : how  do  this  people  get so confused and  complicated  images  done  in pics?, do they program each led?, I doubt it, do you guys know  a program  which allows me to create the led programming  part  from a images to use  it in  a  pic?, here  i leave you a video to  let you know  exactly about what kind  of images I am  talking about, my best  regards,

I don't know how he implemented that.But only logic is that instead of using matrix LED array use single column and using encoder note down that array angle.Now you have virtual matrix of LED and apply same principal you are using in monitor or LCD display or in static 2D array of LED(TRACE -RETRACE by row and colume) that has to do.
