Affine #17

We are now two weeks into this series, so time for a quick recap. The basic idea is to use affine transformations to tilt, stretch, and shrink lines. Always straight, no curves. Then adjust colors to highlight the "top" side of the line, while leaving the other side transparent. See Affine #1 and Affine #2 for more details.

"Top" is in quotes. For example a 180 degree rotation is a affine transformation which turns top into bottom. So "top" depends on the particular transformaion details.

In the initial pictures, the transformations included rotations of many angles, generally close to 0, 45, 90 degrees. The most recent pictures had only small rotations, keeping things close to the horizontal.

This one has a bigger range of angles like the earlier ones. I have added some jitter like the recent ones to break up the straight lines.
