+The Library of course uses the regular orientation. Consider this:
+
+matrix.drawRect(x,y, sizeX, sizeY, matrix.Color888(255,255,255));
+
+x,y are the starting co-ordinates starting from top-left
+
+sizeX, sizeY will be the size of the rectangle we want to draw.
+
+Everything is in pixel (px) logically 1px == 1LED
+
+The ColorXXX() functions are used to define the color "spectrum"
+
+Color333() - 3bit color representation
+Color444() - 4bit color representation
+Color888() - 8bit color representation
+
+To simulate a grayscale is pretty difficult and needs some hacking:

+We have 20 windows at our disposal.
+
+I chose the cheapeast and dirties path possible for the PoC and the following map gives you an overview of the addressing of the windows on the mock-up:
