[[Image:Table de correspondance entre le Bibinaire et les autres notations.svg|520px|thumb|right|Note: eachEach Bibi digit is formed from a square arranging the 1-bits in its binary representation. If only a single bit is 1 a vertical line runs through 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 round 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'''") is a [[hexadecimal]] numeral system first described in 1968<ref>Brevet d'invention n° 1.569.028, ''Procédé de codification de l'information'', Robert Jean Lapointe, demandé le 28 mars 1968, délivré le 21 avril 1969.

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.{{citation needed|date=October 2016}}
