Pencil bending illusion and equidistant 360 degrees point sources

[StasFainer]

I was wondering about the possibility to add a feature like the “beam”, but instead there would be equidistant 360 degrees point sources along the line. I think this can be used for different scenarios, and in particular for the simple “pencil bending illusion”.

Also, in such tool, an option of having the point sources equidistant along a circle could be interesting too, for example to see how such circle transforms under different optical systems, such as an ideal lens, etc.

I also attached two .json files that could be served as a draft for an example of this illusion.
