It's a fun idea, but I'm confused as to why the inventor decided that decoding would rely on reading the bits in order of top-to-bottom, left-to-right. To make it intuitive to readers of French, you'd expect the order to be left-to-right, top to bottom. To make it intuitive to mathematicians, you might expect it to start in the upper right and proceed counterclockwise, as per the numbered quadrants of a Euclidean plane. The 16 symbols themselves will remain the same regardless of the order in which you visit the bits, but the sequential position of each symbol will change.
