Harmonic Lineart
For whatever reason I got interested in thinking about non-constant partitions. So I made this, where it divides up a distance into n pieces so that the ratio of the lengths of each piece to the smallest piece is 2, 3, 4, ... n. It makes for a nice effect, to me, anyhow.
The two tools are for putting a harmonic pattern of points between two endpoints, and a harmonic pattern of segments between four endpoints. For both, you have to say how many you want, but that can be a slider.
