Generating random curves from one endpoint?

hi! im fairly new to grasshopper. i wanted to randomly generate some coral growth that i could eventually 3d print. to do this, it makes most sense to me to connect curves (rails) and circles (face) to a sweep1 component-- but i don’t know how to generate them, the curve rails in specific because i would like the curves to all meet at one point, like this:

im trying to imitate something natural like this… i have seen other similar threads like this but i simply don’t have the experience to understand bringing in more complex plugins like dendro or millipede in.

help appreciated!
