### [ksktozwk] Epstein Didn't Kill Himself minimal QR code

the text EPSTEINDIDNTKILLHIMSELF fits just inside the capacity of the smallest ("version 1") QR code, 21x21 pixels.  (adding spaces between the words, or adding an apostrophe in DIDNT, would increase the size to 25x25, "version 2".)  below is the 21x21 bitmap of pixels as text: 1 = black, 0 = white (background).

`111111100010101111111 100000101011001000001 101110100100001011101 101110101100101011101 101110100010001011101 100000101110001000001 111111101010101111111 000000000010100000000 111110111101110101010 110010000001010100011 101100110101010110011 111101000101000010100 001110111011100001101 000000001111011010101 111111101111001100001 100000100100110010011 101110101110110100001 101110101001001100100 101110101000110010000 100000101111011100101 111111101110101100000`

the image below is the same as the bitmap text above, but with a 4 pixel quiet margin then magnified by 3x.

increasing error correction to level H increases the size to 29x29, and it doesn't matter if we add spaces and an apostrophe, so we do:
