Bibi-binary

At the time, it attracted the attention of André Lichnerowicz, then engaged in studies at the University of Lyon.

The notational system directly and logically encodes the binary representations of the digits in a hexadecimal (base sixteen) numeral.

The graphical and phonetic conception of these symbols is meant to render the use of the Bibi-binary "language" simple and fast.

In addition to unique graphical representations, Lapointe also devised a pronunciation for each of the sixteen digits.

For example: the number written as "2000" in decimal, which translates to "7D0" in conventionally-written hexadecimal, would in Bibi-binary be spoken aloud as "BIDAHO".

Each 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.
