Of course I had no idea how to do this, so I asked my boffin mate Dr James Clewett (star of numerous videos).
He produced three versions for me - ones and zeros in bits; RGB bytes displayed a hexidecimal numbers in bytes; and finally the hexidecimal numbers again as bytes for the gray-scale image.
I don't have more detail about this as yet (but am secretly hoping he'll write guest blog to explain it).
The 0s and 1s version starts like this...
And continues for about 5-6 million digits.
