60 rectangles.

(Continued from 50000 Rectangles #27.) The second option for orientation is to use the phase of the rectangle's corner. The phase of a complex number is the angle (in radians) of the ray from the origin to the complex number. See Complex Number. If the orientation is set to the phase, then every rectangle points away from the center.

Today's image uses the orientation-by-set rule described yesterday. 50000 Rectangles #11 is an example of the basic phase rule.

1000 rectangles.

Today
The weight within a rectangle varies by another random/not random distribution. The result is as if the paint is applied using a sponge.

Ongoing Story
(Continued from 50000 Rectangles #28.) Using the phase for the rectangle orientation is fun the first few times, but gets old quick. However there are enough simple tricks to keep it interesting. Sometimes I move the origin, then the rectangles seem to emanate from a different point. If pi/2 (90 degrees) is added to the phase then the rectangles fit into circles around the origin. Other offsets have different effects, creating spirals for example.

If the orientation is doubled then the rectangles seem to point away from the center on one side and into the center on the other. Similar to field lines around a magnetic pole. Combing different multiples and offsets create enough variations to keep me entertained for the whole series.

50000 Rectangles #14, 50000 Rectangles #18, 50000 Rectangles #25 and many others are examples of variations on the phase rule.

100000 rectangles.

Today
A lot of very thin rectangles. Lines really. Each color set is following a different IFS rule set.

Ongoing Story
(Continued from 50000 Rectangles #29.) Rules have exceptions. All of the color, length, width, orientation rules just described are broken on occasion.

1600000 rectangles.

Each IFS set today consists of a single function. So no randomness, the image is fully deterministic.

Same idea as yesterday. Tamer color palette.
