Originally I am a telecommunications engineer.
Accidentally discovering AA-Patterns more than 16 years ago eventually
lead me to know Bridges and its community.
These patterns are so simple yet so rich, and they do not cease to
inspire me.
So far I found applications for them in pixel art (still and
animated), weaving design, and most recently sampling (in computer
graphics).
Once again, my art work this year is inspired by AA-Patterns.
(Extended) AA Patterns are pixel patterns obtained by bitwise AND
of two constituent bitmaps, one constituent bitmap is made up of
two repeating rows, and the other of two repeating columns. The
two rows (or columns) are made up of a sequence of dashes that
alternate between the two columns, with a single pixel stop before
commencing a new dash in the other row.
AA-Patterns (and their close relative AA-Bitmaps) are two
color-able in an even-odd fashion.
In this artwork I use the decimal digits of pi to supplement the
dash-sequences used to create the pattern.
The resulting pixel pattern is curious: it is random thanks to pi,
but is still organized thanks to the low-entropy AA-Patterns.
Can you see distinguish the 0's, 1's, or 9's?
