Hi Frank,
Hey I think there's a typo here (at least the array size), but you should check it, my eyes are going:)
See below,
Dave
I think:
This:

Should be this:

> {
> 8, 72, 72, 72, 72, 72, 72, 72, // 0 - 7
> 72, 72, 78, 74, 76, 74, 78, 89, // 8 - 15
> 81, 84, 84, 81, 89, 106, 93, 94, // 16 - 23
> 99, 94, 93, 106, 129, 111, 108, 116, // 24 - 31
> 116, 108, 111, 129, 135, 128, 136, 145, // 32 - 39
> 136, 128, 135, 155, 160, 177, 177, 160, // 40 - 47
> 155, 193, 213, 228, 213, 193, 255, 255, // 48 - 55
> 255, 255, 255, 255, 255, 255, 255, 255 // 56 - 63
> };
