Hi community!

Picture:

Demo: [https://codepen.io/prisoner849/pen/ZEjEwmJ](https://codepen.io/prisoner849/pen/ZEjEwmJ)

Working on it was a good reminder of not to call `normalize()` on vectors of zero length 🥲

Its very clever that the distance between the lines remains consistent while it transforms.

@seanwasere Once upon a time I made a prototype of this in js, here: [геометрия - Как найти точки пересечения прямых? - Stack Overflow на русском](https://ru.stackoverflow.com/a/1468387/224917) (Russian, though). And in the demo I tried to port that solution’s idea into vertex shader.
