[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).

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:
