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...
110001101101011011001010111110
And continues for about 5-6 million digits.
