3x NeoMatrix 8x8

[marmilicious]

What if you generate the code for a width 8 by height 24 matrix, and then manually cut/paste to shuffle around the lines in the resulting table?

Here's a example for three 2x2 matrixes, so initially do a 2x6 and get this XYtable:
const uint8_t XYTable[] = {
0, 1,
2, 3,
4, 5,
6, 7,
8, 9,
10, 11
};

Then manually cut/paste like:
const uint8_t XYTable[] = {
0, 1, 4, 5, 8, 9,
2, 3, 6, 7, 10, 11
};

Does that work, or did I reverse something in my brain?

Having an "offset" option, where a starting number could be entered for the first pixel, and it would count up from there instead of zero could be a nice addition too.

If the matrices are actually 8x8 squares (without oddly shaped corners or internal holes) then this tool is not really that useful; it's much easier to map the matrices to LED numbers using a small amount of math rather than a big arbitrary const table.
