50000 Rectangles #26

450 rectangles.

Today
Before now, each rectangle had uniform weight (as defined in 50000 Rectangles #2). Here the rectangle has more weight near the center and less at the edges. Weight affect color overlay and shadows. Also, obviously, there are far fewer than 50000 rectangles today.

Ongoing Story
(Continued from 50000 Rectangles #25.) As described before, the rectangle locations are in N sets of M rectangles. N is small, M is large. N=10, M=5000 for example.

A color is selected for each set. The color is constant within a set, different from set to set. Recall that the locations for each set are determined by different IFS-like function sets. Each set follows a different random distribution. This helps bring out the different characteristics of the different distributions.
