On: Gray code at the pediatrician's office

[llimllib]

sure thing - read the strips in horizontal rows of 10 bits from the top down, giving a white pixel a value of 0 and a black pixel a 1. So, on the gray code strip on the right, we see:

    0000000000
    0000000001
    0000000011
    0000000010
    0000000110
    0000000101

...etc. Does that make sense?
