Large Display: x by y w/ 24 bpp Graphics buffer visualized with neopixel string in zig-zag layout

Thought about this... but the colors are so absurd... and how can you smoothen out setting single pixel? ... it is random that left or right of the pixel a green one shows... just weird.

Here the code to your suggestion - and thank you for jumping on this:

// colorfun2.js

// drawing Lines and setting a Pixel in 9 x 4 and 24 bbp
//
//   0 1 2 3 4 5 6 7 8
// 0 L ~ ~ ~ ~ L L L L
// 1 ~ L ~ ~ P ~ ~ ~ L
// 2 ~ ~ L ~ ~ ~ ~ ~ L
// 3 ~ ~ ~ L ~ ~ ~ ~ L

var npxPin = B15
  , g = Graphics.createArrayBuffer( 9,4,24
            ,{zigzag:true,color_order: "rgb"} ) 
  , clrs = [1573095,7667850,15144960,51510]
  , cdx  = 0
  , cIId = setInterval(function(){ 
        g.setColor(clrs[cdx]);
        g.drawLine(0,0,3,3);
        g.drawLine(5,0,8,0);
        g.drawLine(8,0,8,3);
        g.setPixel(4,1,clrs[cdx]);
        cdx = ++cdx % 4;
      },2000)
  , sIID = setInterval(function(){
        require("neopixel").write(npxPin,g.buffe­r);
      }, 250)
  ; pinMode(B15,"af_opendrain");
