Not sure what you are doing wrong with the loading becuase it works fine for me as it stands.
If you want to keep my grid arrangement but just move it over to the right use something like this
for (var j = 0; j<myArray.length; j++) {
myArray[j][0] += 50;
}
just after the last element of the array has been defined.
You`ll have to drag the background over manually.
EDIT/
Rather than use this, if you take the time to have a look at Scottys grid code posted below and play about with the variables you`ll be in a much better position to make the exact effect you are looking for.
