Bibi-binary

Note: each Bibi digit is formed from a square arranging the 1-bits in its binary representation. If only a single bit is 1 the line starts at the centre and ends in that bit's corner; otherwise it relies on the order of the positions of the 1-bits. When there are exactly two 1-bits, the line passes through the centre. The forms are rounded when there are less than three 1-bits, and use sharp corners when three or four of the bits are 1.

The Bibi-binary system for numeric notation (in French système Bibi-binaire, or abbreviated "système Bibi") was first described in 1968 by Robert "Boby" Lapointe (1922-1972), based on the concept of hexadecimal notation. At the time, it attracted the attention of André Lichnerowicz, then engaged in studies at the University of Lyon. It found some use in a variety of unforeseen applications: stochastic poetry, stochastic art, colour classification, aleatory music, architectural symbolism, etc.
